Digg com_load_typelib
Loads a Typelib
(PHP 4 >= 4.0.7, PHP 5)
Loads a type-library and registers its constants in the engine, as though they were defined using define(). The case_insensitive behaves in the same way as the parameter with the same name in the define() function. typelib_name can be one of the following:
PHP will attempt to resolve the type library in this order, as the process gets more and more expensive as you progress down the list; searching for the type library by name is handled by physically enumerating the registry until we find a match. Note that it is much more efficient to use the com.typelib_file configuration setting to pre-load and register the constants, although not so flexible. If you have turned on com.autoregister_typelib , then PHP will attempt to automatically register the constants associated with a COM object when you instantiate it. This depends on the interfaces provided by the COM object itself, and may not always be possible. Code Examples / Notes » com_load_typelib04-may-2004 03:18
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. Also, check out http://www.php.net/manual/en/faq.com.php to find out how to get COM events working in PHP. ojpp
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. richard dot quadling
