com.allow_dcom

如果打开此选项，PHP 将被允许以一个 D-COM(Distributed

COM)客户方式操作并允许 PHP 脚本在远程服务器上实例化 COM 对象。

com.autoregister_typelib

When this is turned on, PHP will attempt to register constants from

the typelibrary of COM objects that it instantiates, if those objects

implement the interfaces required to obtain that information.

The case sensitivity of the constants it registers is controlled by the

configuration directive.

com.autoregister_verbose

When this is turned on, any problems with loading a typelibrary during

object instantiation will be reported using the PHP error mechanism.

The default is off, which does not emit any indication if there was

an error finding or loading the type library.

com.autoregister_casesensitive

When this is turned on (the default), constants found in auto-loaded

type libraries when instatiating COM objects will be registered case sensitively. See

com.code_page

It controls the default character set code-page to use when passing

strings to and from COM objects. If set to an empty string, PHP will

assume that you want CP_ACP, which is the default

system ANSI code page.

If the text in your scripts is encoded using a different

encoding/character set by default, setting this directive will save you

from having to pass the code page as a parameter to the com class constructor. Please note that by

using this directive (as with any PHP configuration directive), your PHP

script becomes less portable; you should use the COM constructor parameter

whenever possible.

com.dotnet_version

The version of the .NET framework to use for dotnet objects.

The value of the setting is the first three parts of the framework's version number,

separated by dots, and prefixed with v, e.g. v4.0.30319.

com.typelib_file

When set, this should hold the path to a file that contains a list

of typelibraries that should be loaded on startup. Each line of

the file will be treated as the type library name and loaded as

though you had called #cis or #case_insensitive,

then the constants from that library will be registered case

insensitively.
