PHP_value auto_prepend_file /path/to/config.PHP

PHP doc auto_prepend_file string

Specifies the name of a file that is automatically parsed before the main file. The file is included as if it was called with the require function,so include_path is used.

The special value none disables auto-prepending.

编辑：要更加彻底,这些还可以是别名的其他超帧：

$HTTP_SERVER_VARS = &$_SERVER;
$HTTP_POST_FILES = &$_FILES;
$HTTP_SESSION_VARS = &$_SESSION;
$HTTP_ENV_VARS = &$_ENV;
