get_cfg_var
Description
string get_cfg_var ( string option )
Gets the value of a PHP configuration option.
This function will not return configuration information set when the PHP was compiled, or read from an Apache configuration file (using the php3_configuration_option directives).
To check whether the system is using a configuration file, try retrieving the value of the cfg_file_path configuration setting. If this is available, a configuration file is being used.
