Description
string get_cfg_var (string varname)
Returns the current value of the PHP configuration variable
specified by varname, or false if an error
occurs.
It 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.
