VIII. COM support functions for Windows

Introduction

   COM is a technology which allows the reuse of code written in any
   language (by any language) using a standard calling convention and
   hiding behind APIs the implementation details such as what machine the
   Component is stored on and the executable which houses it. It can be
   thought of as a super Remote Procedure Call (RPC) mechanism with some
   basic object roots. It separates implementation from interface.

   COM encourages versioning, separation of implementation from interface
   and hiding the implementation details such as executable location and
   the language it was written in.

Requirements

   COM functions are only available on the Windows version of PHP.

Installation

   There is no installation needed to use these functions; they are part
   of the PHP core.

   The windows version of PHP has built in support for this extension.
   You do not need to load any additional extension in order to use these
   functions.

Runtime Configuration

   The behaviour of these functions is affected by settings in php.ini.

   Table 1. Com configuration options
   Name                           Default Changeable
   com.allow_dcom                 "0"     PHP_INI_SYSTEM
   com.autoregister_typelib       "0"     PHP_INI_SYSTEM
   com.autoregister_verbose       "0"     PHP_INI_SYSTEM
   com.autoregister_casesensitive "1"     PHP_INI_SYSTEM
   com.typelib_file               ""      PHP_INI_SYSTEM
   For further details and definition of the PHP_INI_* constants see
   ini_set().
