更新日志

版本 说明
5.4.0 This function became available under FastCGI. Previously, it was supported only when PHP was installed as an Apache module.
4.3.3

Note:

从 PHP 4.3.3 起,也可在 Netscape/iPlanet/SunONE Web 服务器的 NSAPI 服务器模块 使用此函数。

4.3.0 Became an alias for apache_request_headers(). Essentially, it was renamed. This is because this function only works with Apache.
