><P
> COM is an acronym for Component Object Model; 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 loadaed 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.
</P
><P
> 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 utilitizes the OLE
Automation interfaces to allow you to create and call compatible objects
from your scripts. Technically speaking, this should really be called
the "OLE Automation Extension for PHP", since not all COM objects are OLE
compatible.
</P
><P
> 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.
</P
><P
> Starting with PHP 5, this extension (and this documentation) was
rewritten from scratch and much of the old confusing and bogus cruft has
be removed. Additionally, we support the instantiation and creation of
.Net assemblies using the COM interoperability layer provided by
Microsoft.

> Many COM objects expose their properties as arrays, or using array-style
access. In PHP 4, you may use PHP array syntax to read/write such a
property, but only a single dimension is allowed. If you want to read a
multi-dimensional property, you could instead make the property access
into a function call, with each parameter representing each dimension of
the array access, but there is no way to write to such a property.
