這是配置指令的簡短說明。

com.allow_dcom

如果打開此選項，PHP 將被允許以一個 D-COM（Distributed COM）客戶方式操作並允許 PHP 指令碼在遠端伺服器上實例化 COM 對象。

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_load_typelib() for more details.

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 com_load_typelib(). The constants will be registered persistently, so that the library only needs to be loaded once. If a type library name ends with the string #cis or #case_insensitive, then the constants from that library will be registered case insensitively.
