( string typelib_name [, bool case_insensitive] )
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:
The filename of a .tlb file or the executable module
that contains the type library.
The type library GUID, followed by its version number, for example
The type library name, e.g. Microsoft OLE DB ActiveX Data
Objects 1.0 Library.
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
configuration setting to pre-load and register the constants,
although not so flexible.
If you have turned on
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
