运行时配置

这些函数的行为受 php.ini 中的设置影响。

COM 配置选项

名字	默认	可修改范围	更新日志
com.allow_dcom	"0"	PHP_INI_SYSTEM
com.autoregister_typelib	"0"	PHP_INI_ALL
com.autoregister_verbose	"0"	PHP_INI_ALL
com.autoregister_casesensitive	"1"	PHP_INI_ALL
com.code_page	""	PHP_INI_ALL
com.dotnet_version	""	PHP_INI_SYSTEM	As of PHP 8.0.0
com.typelib_file	""	PHP_INI_SYSTEM

有关 PHP_INI_* 样式的更多详情与定义，见 配置可被设定范围。

这是配置指令的简短说明。

com.allow_dcom

启用后，将允许 PHP 作为 D-COM（分布式 COM）客户端运行，并允许 PHP 脚本在远程服务器上实例化 COM 对象。

com.autoregister_typelib

启用后，PHP 尝试从已实例化的 COM 对象的类型库中注册常量，前提是这些对象实现了获取信息所需的接口。注册的常量是否区分大小写，由 com.autoregister_casesensitive php.ini 控制。

com.autoregister_verbose

启用时，在对象实例化期间加载类型库出现的任何问题都会使用 PHP 的错误机制报告。默认为 off，如果查找或者加载类库出现错误则不会发出任何指示。

com.autoregister_casesensitive

启用时（默认），实例化 COM 对象时，在自动加载类型库中找到的常量将区分大小写进行注册。有关详细信息，请参阅 com_load_typelib()。

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

用于 dotnet 对象的 .NET 框架版本。设置的值是框架版本号的前三部分，以点分隔，并以 v 作为前缀，例如 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.
