In case any of you were wondering what com_load_typelib actually DOES, I have found that it loads constants\enums that the COM obeject has defined. The example below is using the Nero COM object (from Nero Burning rom, version 6+). The Nero object defines a bunch of constants, but they can not be used as PHP constants unless you use the mentioned function. So the example below will work just fine:
<?php
$aNero = new COM("Nero.Nero") or die ("Nero didn't load, too bad");
com_load_typelib("Nero.Nero");
$aNero->GetDrives(NERO_MEDIA_CD);
?>
But this one will not, since PHP will return a message saying that the constant is undefined:
<?php
$aNero = new COM("Nero.Nero") or die ("Nero didn't load, too bad");
$aNero->GetDrives(NERO_MEDIA_CD);
?>
This one took me a while to figure out, hope it helps.

Hello PHP community, I want to help in a problem I found in this COM built-in function: com_load_typelib(), when I executed it in order to open a COM Server process (for example: Word, Excel, etc.) I was in trouble to release the object from memory, I figured it out, this is the solution:
Change a configuration in the php.ini:
; autoregister constants of a components typlib on com_load()
com.autoregister_typelib = true
When com.autoregister_typelib directive is true, PHP parser manage the COM server type library, I hope it helps.

<?php
// Some servers may have an auto timeout, so take as long as you want.
set_time_limit(0);
// Show all errors, warnings and notices whilst developing.
error_reporting(E_ALL);
// Used as a placeholder in certain COM functions where no parameter is required.
$empty = new VARIANT();
// Load the appropriate type library.
com_load_typelib('Word.Application');
// Create an object to use.
$word = new COM('word.application') or die('Unable to load Word');
print "Loaded Word, version {$word->Version}\n";
// Open a new document with bookmarks of YourName and YourAge.
$word->Documents->Open('C:/Unfilled.DOC');
// Fill in the information from the form.
$word->Selection->GoTo(wdGoToBookmark,$empty,$empty,'YourName'); // Note use of wdGoToBookmark, from the typelibrary and the use of $empty.
$word->Selection->TypeText($_GET['YourName']);
$word->Selection->GoTo(wdGoToBookmark,$empty,$empty,'YourAge');
$word->Selection->TypeText($_GET['YourAge']);
// Save it, close word and finish.
$word->Documents[1]->SaveAs("C:/{$_GET['YourName']}.doc");
$word->Quit();
$word->Release();
$word = null;
print "Word closed.\n";
?>
The example document is ...
Hello [Bookmark of YourName], you are [Bookmark of YourAge] years old.
and it would be called ...
word.php?YourName=Richard%20Quadling&YourAge=35
Regards,
Richard.
