get_cfg_var — Gets the value of a PHP configuration option

### 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.

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.

### Parameters

`option`

  The configuration option name.

### Return Values

Returns the current value of the PHP configuration variable specified by `option`, or `FALSE` if an error occurs.
