php.ini 配置段列表

This list includes the php.ini sections you can set to configure your PHP setup on a per Host or Path basis. These sections are optional.

These sections don't directly affect PHP. They are used to group other php.ini directives together and to get them to act upon a particular host or on a particular path.

These sections are used only in CGI/FastCGI mode and they can not set extension and zend_extension directives.
