I couldn't find an example anywhere on what I was trying to do.  After taking bits from everyone I ended up with something that worked.



Im using Crystal Reports 10, MS SQL Server 2005, Apache2, and PHP5.



My report uses an SQL Store Procedure and passes some parameter to get the report data, so our PHP must set the database logon info and pass the parameters.



Below is the solution I came up with:



<?php



//------  Variables ------

$my_report = "C:\\Apache2\htdocs\\test\\MyReport.rpt";  //This must be the full path to the file

$my_pdf = "C:\\Apache2\htdocs\\test\\MyReport.pdf";



//------ Create a new COM Object of Crytal Reports 10 ------

$ObjectFactory= new COM("CrystalReports10.ObjectFactory.1");



//------ Create a instance of library Application -------

$crapp = $ObjectFactory->CreateObject("CrystalDesignRunTime.Application.10");



//------ Open your rpt file ------

$creport = $crapp->OpenReport($my_report, 1);



//------ Set database logon info ------

$creport->Database->Tables(1)->SetLogOnInfo("MYSERVER", "Database", "user", "password");



//------ Suppress the Parameter field prompt or else report will hang ------

$creport->EnableParameterPrompting = 0;



//------ DiscardSavedData make a Refresh in your data -------

$creport->DiscardSavedData;

$creport->ReadRecords();



//------ Pass formula fields --------

$creport->FormulaFields->Item(1)->Text = ("'My Report Title'");

$creport->ParameterFields(1)->AddCurrentValue ("FirstParameter");

$creport->ParameterFields(2)->AddCurrentValue (2000);



//------ Export to PDF -------

$creport->ExportOptions->DiskFileName=$my_pdf;

$creport->ExportOptions->FormatType=31;

$creport->ExportOptions->DestinationType=1;

$creport->Export(false);



//------ Release the variables ------

$creport = null;

$crapp = null;

$ObjectFactory = null;



//------ Embed the report in the webpage ------

print "<embed src=\"MyReport.pdf\" width=\"100%\" height=\"100%\">"



?>



Obviously there's plenty of room for refinement in there, but it works and should get you going on the right track.  I also found that during testing, the script was hanging before supressing the parameter prompt. Once this had happened, some exports that had been working earlier stopped completely and wouldn't work again untill I restarted Apache.  This might be something worth doing if you keep having issues after a script has hung.

This is my first php.net comment so go easy on me :)



I was having trouble using COM to convert from ppt/pptx to an image for every slide (this works for outputting pdf,html,pptx->ppt, etc)



$app = new COM("PowerPoint.application") or die("Unable to instantiate PowerPoint");

$app->Visible = true;

$pres = $app->Presentations->Open("E:/tmp/test.pptx") or die ("Could not open presentation");

$app->Presentations[1]->SaveAs("E:/tmp/outdir",18);

$app->Presentations[1]->Close();

$app->Quit();

$app = null; 



This code converts pptx to a png of every frame. Thats what 18 stands for (Its a class constant, you can see all the other formats here: http://msdn.microsoft.com/en-us/library/bb265906.aspx)



Hope this helps someone. Feel free to email me at the address above.

Using the DynamicWrapper from http://freenet-homepage.de/gborn/WSHBazaar/WSHDynaCall.htm and after registering it via "regsvr32 dynwrap.dll", you can easily set output colors to make colorful CLI scripts even on Windows.



<?php



$dw = new COM('DynamicWrapper');  // needs dynwrap.dll (regsvr32 dynwrap.dll)



// register needed features

$dw->Register('kernel32.dll', 'GetStdHandle', 'i=h', 'f=s', 'r=l');

$dw->Register('kernel32.dll', 'SetConsoleTextAttribute', 'i=hl', 'f=s', 'r=t');

$dw->Register('kernel32.dll', 'SetConsoleTitle', 'i=s', 'f=s', 'r=l');



// get console handle

$ch = self::$dw->GetStdHandle(-11);  // -11 = STD_OUTPUT_HANDLE



?>



After these initialization steps, you can set the console output color using:



<?php

$dw->SetConsoleTextAttribute($ch, 14);

echo 'This is yellow text!';

$dw->SetConsoleTextAttribute($ch, 7);

echo 'Back to normal gray!';

?>



Using SetConsoleTitle you can even set the title displayed in the console window.



Color values are 0..7 for dark colors and 8..15 for light colors. Sequence is (black/silver, blue, green, cyan, red, magenta, yellow/brown, white/gray). I also found that if you add 16384 to the value, it should be inverse. 32768 added should get underlined text. But these latter two didn't work for me.

If you ever want to save an Excel(.xls) file into the Office Excel 2003 XML format, just use



$excel->Workbooks[1]->SaveAs('new_file_name.xml', 46);



That's the number you need, 46.

Thanks to paul at completewebservices who added a note earlier; I have used his code to solve a particularly difficult issue with the Crystal 9 runtime component. For some reason, VBA/VBS can pass a native Date type as a parameter to a Crystal Report requiring a date, but in PHP I've tried all manner of strings, unix timestamps, COM variant dates etc and all of these resulted in a com_exception.



My solution was to employ VBScript to borrow the CDate function, which works correctly. Not the most elegant of solutions, but this parameterised approach is to be preferred to search-n-replacing the RecordSelectionFormula string. Of course if anyone here has an even better approach, do post it here - I am sure it would be of use.



<?php

// $rptParam is a report parameter object having a type of date

$oScript = new COM("MSScriptControl.ScriptControl");

$oScript->Language = "VBScript";

$oScript->AllowUI = false;

$oScript->AddObject('rptParam', $rptParam, true);

$oScript->AddCode('Function SetDateParameter(strDate)

rptParam.AddCurrentValue(CDate(strDate))

End Function');

$oScript->Run("SetDateParameter", "25 April 2006");

?>

My previous notes about Crystal Reports have vanished away, but anyway I was up to correct them.



The code above connects to COM (beware of the version number! search on the Registry Editor for the correct name to put in $COM_Object), opens a report from a file ($my_report), reload records from database and then exports it to a PDF file ($my_pdf).



* IMPORTANT * this code, when invoked from the browser (I'm using Apache) AND with a report that connects to a ODBC database, does not work (the problem is specificly the line ReadRecords(), but may arise without it too when data is not saved into the report file).



But when you run this code by PHP-CLI (that is, by the command line), it works ok! I bug-reported this, but have no answer till now ( give it a vote, if you thing it's important: http://bugs.php.net/bug.php?id=36959 ).



Also, exceptions may arise, so put it on a try_catch block.

It seems that PHP does not support setting of properties with arguments.  This is how I got around the problem:



        // Object with method I want to set

        $auth = new COM("AUTHXOCX.AuthXOCXCtrl.1");



        // ScriptControl 

        $oScript = new COM("MSScriptControl.ScriptControl");

        $oScript->Language = "VBScript";

        $oScript->AllowUI = TRUE;



        // Add out object to the control

        $oScript->AddObject('auth', $auth, true);



        // Create a VBScript function that allow me to set them

       $oScript->AddCode(

'Function fixAccess(accessname)

    auth.AuthDataReferrerEnabled(accessname) = 1

    auth.AuthDataAuthentiXDBEnabled(accessname) = 0

End Function');



        // Execute function

        $oScript->Run("fixAccess", $dir);

To use the windows speech system install the "Speech SDK 5.1 for Windows� applications" from the Microsoft homepage (free download).

Then you can do Text2Speech like this:



$voice = new COM("SAPI.SpVoice");

$voice->Speak("Hello, lets have a conversation");

If your PHP is configured as ISAPI module then the COM object you create in ur php page will use the same memory space as the web server. If your COM object takes too much memory then this may force some COM error as PHP does not handle the memory usage of COM itself. And also Web server doesnt know what do to free COM memory. But if you use PHP as CGI then PHP itself handle the memory usage of COM. Once in a script where i used COM and PHP as ISAPI module i got unknown COM error.But when i used PHP as CGI there was no error. So those who want to use COM object in your application please be careful about it.

If you can get the old "TaskScheduler.dll" and register it, it is quite simple to handle and start Windows tasks from PHP.

This is extremely useful when you got things to do which must be run in a different user context. Prepare a task with the user and use PHP & Com to build a webinterface for it.



Here is an example how to start a Windows task:



  function start_task ($taskname) {

    $SchedObj = new COM("Scheduler.SchedulingAgent.1");

    foreach ($SchedObj->Tasks as $task) {

      if (strtolower( (string) $task) == strtolower( $taskname.".job" )) {

         $task->Run();

      }

    }

  }



I'm also working on a class to handle infos, adding and removing of tasks via PHP. If you are interested drop me a line.

Getting * directory * permissions ( attributes ) with COM



PHP (5) example...



<?

    $dir = 'e:/www/docs/www/docs/junk/';



    define ( 'READ_ONLY', 1 );

    define ( 'IS_HIDDEN', 2 );

    define ( 'IS_SYSTEM', 4 );



    $hold = array ();



    $obj = new COM ( 'scripting.filesystemobject' );



    if ( is_object ( $obj ) )

    {

        $all = $obj->getfolder ( $dir );



        foreach ( $all->subfolders AS $directory )

        {

            if ( substr ( $directory->name, - 3 ) != 'cnf' )

            {

                $hold[$dir . $directory->name . '/'] =  array ( 'read_only' => ( ( $directory->Attributes & READ_ONLY ) <> 0 ? 1 : 0 ), 'is_hidden' => ( ( $directory->Attributes & IS_HIDDEN ) <> 0 ? 1 : 0 ), 'is_system' => ( ( $directory->Attributes & IS_SYSTEM ) <> 0 ? 1 : 0 ) );

            }

        }



        $obj = null;

    }

    else

    {

        echo 'sorry can not crate object: file_system_object';

    }



    print_r ( $hold );

?>



To do the same thing for * files * with in the directory named in $dir, change above ( foreach() ) to what is below...



        foreach ( $all->files AS $file )

        {

            $hold[$file->name] =  array ( 'read_only' => ( ( $file->Attributes & READ_ONLY ) <> 0 ? 1 : 0 ), 'is_hidden' => ( ( $file->Attributes & IS_HIDDEN ) <> 0 ? 1 : 0 ), 'is_system' => ( ( $file->Attributes & IS_SYSTEM ) <> 0 ? 1 : 0 ) );

        }



pretty much anything you could think of doing in windows can be done using PHP and COM...

Getting IE to the foreground

If you are using a command line (CLI) version of PHP on a Win32 platform (e.g. XP Pro, SP2), you might want to have output directed to IE (perhaps you'll want to work with the output there) when Popup does not suffice (see my earlier post, below).



It's easy enough to get an instance of IE using $ie = new COM("InternetExplorer.Application");.  The problem is, you don't necessarily see it in the foreground (especially if you already have one open) and who wants to waste keystrokes getting to it?  The code below has been working for me (If you want to do other adjustments (e.g. $ie->Document->ParentWindow->resizeTo(800,500); or $ie->Document->Body->bgColor = "yellow";), doing them before the $ie->Visible = true; line will avoid screen distractions):



<?php

function newIEtoForeground($title, $evtPrefix="") {

    // brings new instance of IE to foreground with title $title

    if (!$extPrefix) $ie = new COM("InternetExplorer.Application");

    else $ie = new COM("InternetExplorer.Application", $evtPrefix);

    $ie->Navigate2("about:blank");

    $oWSH = new COM("WScript.Shell");

    while ($ie->ReadyState!=4) usleep(10000);



    $ie->Document->Title = ($tmpTitle = mt_rand());  //unique title

    $ie->Visible = true;

    while (!$oWSH->AppActivate("$tmpTitle - M")) usleep(10000);



    $ie->Document->Title = $title;

    $ie->Document->ParentWindow->opener="me";  // allows self.close()

    return $ie;

}

?>

Basic Windows IO

If you are using a command line (CLI) version of PHP on a Win32 platform, you might like to have a simple graphical interface to get input and output.  The following gives an illustration for both.



<?php

    // first we get some input

    $oScript = new COM("MSScriptControl.ScriptControl");

    $oScript->Language = "VBScript";

    $title = "I/O Demo: Input half";

    $initial = "Change this value";

    $prompt = "Please enter a value";

    

    $code = <<<EOF

Function getInput()

    inVal = InputBox("$prompt", "$title", "$initial")

    getInput = inVal         'how return values are assigned in VB

End Function

EOF;



    $oScript->AddCode($code);

    $input = $oScript->Eval("getInput()");    

    if (gettype($input)=="NULL") $input = "Input box was cancelled";



    // now we show some output

    $oWSH = new COM("WScript.Shell");

    $title = "I/O Demo: Output half";

    $timeout = 2;        // 0 for no timeout

    $style = 0 + 48;    // buttons to show + alert symbol

    $oWSH->Popup($input, $timeout, $title, $style);

?>



This is example is overblown for illustrative purposes.  The whole input part collapses if the amount of code used is a single statement.  So, this would have sufficed:

$code = "InputBox(\"$prompt\", \"$title\", \"$initial\")";

$input = $oScript->Eval($code);



This technique exposes quite a bit of scripting power tied into the Windows operating system and VBScript.  However, you should have a really specific reason for using it since VBScript tends to be dog slow when compared to PHP in my tests.  Simple IO like this is good, however, and the popup size can be quite large.  Furthermore, this could be a viable route to go for accessing WinAPI's.



http://www.ss64.com/wsh/popup.html shows some documentation for $oWSH->Popup

if you ever need to connect to an access database (on the server, using the IIS or APACHE user account), here is code below that can help to ease the process.  It is written like this because we have a MySQL as well as an Access database and need to be able to switch back and forth.  The runQuery function will return a 2 dimensional array and can use column names or numbers for the index of the internal arrays.  External arrays are always integer-indexed.  We also have found issues with Access staying open and growing from 7MB to 2.5GB within two hours, so we open and close it each time we run a query.  If it is not a select query it will return TRUE.  if it fails with errors, it will return false.



There is a showErr flag that we mostly only use for MySQL, since you can output MySQL errors without PHP errors.  Access doesn't appear to be that friendly.



<?php



function runQuery(&$conn,

                    $strSQL,

                    $associative=true,

                    $debug=false,

                    $showErr=false) {     

    return runMSQuery($conn,$strSQL,$associative,$debug,$showSQL,$showErr); 

    //return runMyQuery($conn,$strSQL,$associative,$debug,$showSQL,$showErr); 

}



function openMSDB($dbfile="c:/path/and/filename.mdb") {

    if (!@$conn = new COM("ADODB.Connection")) 

        exit("Unable to create an ADODB connection<br>");

    $strConn = "DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=".$dbfile; 

    @$conn->open($strConn); 

    if($conn->State == 0) return false;

    return $conn;

}



function closeMSDB(&$conn) {

    @$conn->Close();

    $conn = null;

    $rtn = false;

    if($debug) $rs = $conn->execute($strSQL);

    else $rs = @$conn->execute($strSQL);



    if(!$rs) {

        if($showErr) echo "Error running SQL.<br>\n";

        closeMSDB($conn);

        return false; 

    }

    if ($rs->State == 0) {

        closeMSDB($conn);

        return true;

    } else {    

        $rows=0;

        while(!$rs->EOF) {

            for($i=0;$i<$rs->Fields->count;$i++) {

                if($associative) $rtn[$rows][$rsf->Name] = $rsf->value;

                else $rtn[$rows][$i] = $rsf->value;

            }

            $rows++;

            $rs->MoveNext();

        }

        if($rs->State != 0) $rs->Close();

        $rs = null;

    }

    if($debug) var_dump($rtn);

    closeMSDB($conn);

"Keeping an instance of a Server object loaded"



When dealing with COM objects like 'Word' or 'Excel' you are pretty

much dealing with personal COM type objects. The reason I say this

is because they in no way have any direct relationship to a real COM

server object. The differences between a 'Server COM Object' and a

'Personal COM Type Object' are great. Server COM objects, do not contain

and properties or methods related to any type of program dialog.



Most Enterprise COM objects are designed to run under IIS where they

are loaded into the server process. So once the first instance call is

made or when the server is started the object loads it properties, methods

and data related to the service the object provides!



Many objects load large data set(s) 10 MB to 200 MB into memory, this makes

any process after the initial loading of the object fast and very system

friendly!



In PHP, when an initial instance of an object is loaded some where in a

PHP script, PHP will check if an instance of the object is already running

if it is, then it will use that instance. If it can not find an instance to

the object running, it will create a new instance to the object!



In the case of personal COM type objects, you can point to a running instance

of an object, and reference that instance...



<?



$obj = new COM ( 'X:\reports\june.doc' );



?>



For Server type COM objects that load large data set(s), you really have no option

because each script run will unload the instance at the end of the script's run time.

Unless another http request is running and the new http request can access the other

object instance, you will have to load all the objects properties and methods and data

set(s) used by the object!



One way to work around this is to write a wrapper that can load the object into the

PHP or the Server process! I did this for the objects I use.



Another unorthodox way is to load your web browser to a PHP script that uses a combination

of ignore_user_abort(), set_time_limit(), load the object, sleep();!



Before I wrote the wrapper for a 'Map Server Object' I use in one of my project. I used

the 'unorthodox way' for almost a year and had over 15,000 object requests a day, and

never did the instance of the object ever have to start a new instance, ie: reload all the properties and methods and data

set(s) used by the object!



Like I said this is a very 'unorthodox way' to keep an object loaded, but it works!



set the object 'My.Object' in the script, call the script from the browser, then close the browser!



<?



    ignore_user_abort ( 'true' );



    set_time_limit ( 0 );



    com_load_typelib ( 'My.Object' ) or die ( 'Could not load TypeLib' );



    $obj = new COM ( 'My.Object' ) or die ( 'Could not load object' );



    $obj = null;



    sleep ( 63166608000 ); // one year

I have searched for ways to open and read an excel document and I found some information which I thought that I would document.  Information on the object model to help with programming COM objects can be found in your MS Office help files, search for VBA*.chm.

Also, here is a script that I used to pull a cell from each worksheet, complete w/ variable for pathnames & worksheets.  This script also closes excel completely.  The coding might be dirty, but it gets the job done.

--------copy from here-----------

<pre>

<?PHP

$filename = "c:/spreadhseet/test.xls";

$sheet1 = 1;

$sheet2 = "sheet2";

$excel_app = new COM("Excel.application") or Die ("Did not connect");

print "Application name: {$excel_app->Application->value}\n" ; 

print "Loaded version: {$excel_app->Application->version}\n";

$Workbook = $excel_app->Workbooks->Open("$filename") or Die("Did not open $filename $Workbook");

$Worksheet = $Workbook->Worksheets($sheet1);

$Worksheet->activate;

$excel_cell = $Worksheet->Range("C4");

$excel_cell->activate;

$excel_result = $excel_cell->value;

print "$excel_result\n";

$Worksheet = $Workbook->Worksheets($sheet2);

$Worksheet->activate;

$excel_cell = $Worksheet->Range("C4");

$excel_cell->activate;

$excel_result = $excel_cell->value;

print "$excel_result\n";

#To close all instances of excel:

$Workbook->Close;

unset($Worksheet);

unset($Workbook);

$excel_app->Workbooks->Close();

$excel_app->Quit();

unset($excel_app);

?>

</pre>

Here's a simple example of printing formatted templates with MS Word.





To begin with, I've already built my invoice in Word and saved it as an RTF file.


In this case, I'm using "sampleInvoice.php" 





Fields that will be replaced have been marked as ||CUSTOMER ID|| and so on. 





<?php


$dataText = "";





// open the file


if(!($fp= fopen ("C:\wordTest\sampleInvoice.rtf", "r"))) die ("Can't open");


$dataText = fread($fp, 2000000);


fclose ($fp);





// replace the template fields


$dataText = str_replace ("||CUSTOMER ID||",$customerIDValue, $dataText);





// save the file as an rtf


$timeStamp = time();


$saveFile = "C:/wordTemp/".$timeStamp."-invoice-".$customerIDValue.".rtf";


if(!($fq= fopen ($saveFile, "w+"))) die ("Can't open");


fwrite ($fq, $dataText);


fclose ($fq);





// initialize the word components


$word = new COM("word.application") or die("Unable to instantiate Word"); 





print "Loaded word version ($word->Version)\n";


$word->visible = true;


$word->Documents->Add();





// open the file


$word->Documents->Open("$saveFile");





// output the file to the default printer


$word->ActiveDocument->PrintOut(1);





// shutdown word


$word->Quit();


?>

Changing Fields (Not FORMFIELDS) In MS Word....





Searched most of the afternoon for this, as it is something needed here for our projects.  Maybe this can help someone else as well.





<?php


$input = "x:\\path\\to\\test.doc";


$word = @new COM("word.application") or die("Unable to instantiate Word"); 


print "Loaded Word, version {$word->Version}\n<br>";


$word->Visible = 1;


print "Set Word To Visible<br>";


$word->Documents->Open($input);


print "Opened $input<br>";


$word->Activate;


print "Activated Word<br>";





print "Editing Fields<br>";


$Field = $word->ActiveDocument->Fields(1);


$fieldData = $Field->Result;


$fieldData->Text = "Testing";





// Print the document.


$word->Printout();





// closing word


$word->Quit();





// free the object


$word->Release();


$word = null;

If you wnat to connect to Access MDB Library you can use this small "progy". It works so, that if someone other accesses the library, it waits for so long to access it again because (as i know) MDB librarys can be accessed only once at the same time.





<?php


function mdb($sql, $array = 0, $base = "Base.mdb", $timelimit = 5)


    {


    $r_items = array();


    $c = new COM("ADODB.Connection");


    $r = false;


    $time = time();


    $process = $i = 0;


    while($r == false && $process <= $timelimit)


        {


        $deb = $c->open('DRIVER={Microsoft Access Driver (*.mdb)}; Dbq='. realpath($base) .';');


        $r = $c->execute($sql);


        $process = time() - $time;


        }


    if($process >= $timelimit) exit("mdbSQL Query Timeout!");


    if(strtolower(substr($sql, 0, 6)) == "insert" or strtolower(substr($sql, 0, 6)) == "update" or strtolower(substr($sql, 0, 6)) == "delete") return true;


    $num_fields = $r->fields->count();


    while (!$r->EOF)


        {


        for($j = 0; $j < $num_fields; $j++)


            {


            $key = $r->Fields($j);


            if($array == 0) $r_items[$i][$key->name] = $key->value;


            else $r_items[$i][$j] = $key->value;


            }


        $i++;


        $r->MoveNext(); 


        }


    $r->close();


    $c->close();


    $r = null;


    $c = null;


    return $r_items;


    }


?>





I got the source from the Manual, what i did is that i made it more compatible and user frendly. :)





I hope it could some day help someone so as it did me...

Here's an example/comparison of VBScript vs PHP's COM component to connect to an IIS Webserver.


The examples backup the IIS MetaBase (your server's website(s) configuration) in IIS.





VBScript:


  Dim obj, iFlags 


  Set obj = GetObject("IIS://LocalHost") 


  ' Backup to next available version number. 


  ' Set flags to save the metabase first and 


  ' force the backup even if save fails. 


  iFlags = (MD_BACKUP_SAVE_FIRST or MD_BACKUP_FORCE_BACKUP)


  obj.Backup "MyBackups", MD_BACKUP_NEXT_VERSION, iFlags


  ' Note: The above was copied from Microbucks.


  ' This is how you would have to do it.


  ' i.e. use the actual constant's value.


  iFlags = (2 or 4)  


  obj.Backup "MyBackups", &HFFFFFFFF, iFlags





PHP:


  <?php


  $obj = new COM("IIS://LocalHost")or die("Unable to instantiate IIS");  


  $err = com_invoke ($obj, "Backup", "MyBackups", "&HFFFFFFFF", 2|4 );


  $obj = null;


  print "err=".$err; // returns 0 on success


  ?>

To mstaiger 

I have encountered the same problem you report.

I tried to use the above code for a word document but it doesn't works, although the same code was good if i use it on a excel sheet.



The solution is explained at the following link :

If you want to use a DSN-less connection to a database (access for example) and return the results of a query as a multidimensional array with the fieldnames as identifier try this. Hope it helps someone :-)


--------------------------------------------------------





<?php


function db($sql) {


    $c = new COM("ADODB.Connection");


    $c->open('DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=' . realpath("relative_path/db.mdb"));


    $r = $c->execute($sql);


    $i = 0;


    $num_fields = $r->fields->count();


    while (!$r->EOF)


        {


            for($j = 0;$j<$num_fields;$j++) {


            $key = $r->Fields($j);


            $r_items[$i][$key->name] = $key->value;


        }


        $i++;


        $r->MoveNext(); 


    }


    $r->close();


    $c->close();


    $r = null;


    $c = null;


    return $r_items;


}


?>





--------------------------------------------------------


use it like this:


--------------------------------------------------------


<?php


$results = db("SELECT field_a, field_b FROM table");


foreach($result as $i => $item) {


    echo $item['field_a'];


    echo $item['field_b'];


}


?>


--------------------------------------------------------


You can also use: print_r($result); if you want the structure of the array to be printed.

It should be noted that to run anything that needs to interact with the UI (the word example), one needs to ensure that the process that the Web server is running under can access the UI.  For Apache, this is an option in the Services control panel.

The above Word example did not work for me when I tried it using Office 2000. I had to install the Office 2000 SR 2 upgrade to get everything working. It seems that the upgrade fixes some problems with permissions that affect PHP and some other applications that use COM.

In order to get the Word exaple running, do the following on the server side.

Worked for me...

1. Click START-->RUN and enter "dcomcnfg"

2. In the "Applications" tab, go down to "Microsoft Word Document"

3. Click PROPERTIES button

4. Go to the "Security" Tab

5. Click "Use custom access permissions", and then click EDIT

6. Click ADD and then click SHOW USERS

7. Highlight the IIS anonymous user account (usually IUSR_<machinename>), click ADD

8. Go back to the "Security" tab by hitting OK 

9. Click "Use custom launch permissions", and the click EDIT

10. Click ADD and then click SHOW USERS

11. Highlight the IIS anonymous user account (usually IUSR_<machinename>), click ADD

12. Hit OK, and then hit APPLY. 



Also, you should look at the "Identity" tab in the Microsoft Word Document PROPERTIES and see that it is set to "Interactive User" 

  



ALSO, log into the machine AS the IUSR_<machinename> account, start word, and make sure to click through the dialog boxes that Word shows the first time it is run for a certain user.  In other words, make sure Word opens cleanly for the IUSR_ user.

For Access to Ms Access


use another Provider like this:





<?php


$conn = new COM("ADODB.Connection") 


or die("Cannot start ADO");


$conn->Open("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=./thefile.mdb;");


$rs = $conn->Execute("SELECT * FROM thetable");


?>

The example above (MS Word) is quiet unsatisfying, as I find. Especially since I couldn't find anybody who actually got it running, including myself. 





You might therefore give this Powerpoint-example a chance:


----------------------------------


#Instantiate a PowerPoint object.


$ppoint = new COM("PowerPoint.application") or die("Unable to instantiate PowerPoint");





<?php


#Create a new presentation


$ppoint->Presentations->Add() or die ("Could not create presentation");





//Add a slide


$slide=$ppoint->Presentations[1]->Slides->Add(1,1);





//Get the name of this slide


$slidename = $slide->Name();


echo"<br>slidename : $slidename";





//Change the name of this new slide


$slide->Name = "New Slidename";


$slidename = $slide->Name();


echo"<br>NEW slidename : $slidename";





//Save the presentation


$ppoint->Presentations[1]->SaveAs("c:/InetPub/www/test.ppt");


$ppoint->Presentations[1]->Close();





//closing powerpoint


$ppoint->Quit();





//free the object


$ppoint->Release();


$ppoint = null;


-----------------------


?>





the config is : 


w2k-server/office2k/iis5/php 4.1.1 isapi





If you happen to run into a working word2k-example, please let me know.
