COM is an acronym for <literal>Component Object Model</literal>; it is an object orientated
|
|
layer (and associated services) on top of DCE RPC (an open standard) and
|
|
defines a common calling convention that enables code written in any
|
|
language to call and interoperate with code written in any other language
|
|
(provided those languages are COM aware). Not only can the code be
|
|
written in any language, but it need not even be part of the same
|
|
executable; the code can be loaded from a DLL, be found in another
|
|
process running on the same machine, or, with DCOM (Distributed COM), be
|
|
found in another process on a remote machine, all without your code even
|
|
needing to know where a component resides.

There is a subset of COM known as OLE Automation which comprises a set of
|
|
COM interfaces that allow loose binding to COM objects, so that they can
|
|
be introspected and called at run-time without compile-time knowledge of
|
|
how the object works. The PHP COM extension utilizes the OLE
|
|
Automation interfaces to allow you to create and call compatible objects
|
|
from your scripts. Technically speaking, this should really be called
|
|
the "<literal>OLE Automation Extension for PHP</literal>", since not all COM objects are OLE
|
|
compatible.

Now, why would or should you use COM? COM is one of the main ways to glue
|
|
applications and components together on the Windows platform; using COM
|
|
you can launch Microsoft Word, fill in a document template and save the
|
|
result as a Word document and send it to a visitor of your web site. You
|
|
can also use COM to perform administrative tasks for your network and to
|
|
configure your IIS; these are just the most common uses; you can do much
|
|
more with COM.

Starting with PHP 5, this extension (and this documentation) was
|
|
rewritten from scratch and much of the old confusing and bogus cruft has
|
|
been removed. Additionally, we support the instantiation and creation of
|
|
.Net assemblies using the COM interoperability layer provided by
|
|
Microsoft.
