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.

See also ini_get().

Regarding the statement by the earlier poster that:



"Unfortunately, you almost never want to know the original value in the config file. Instead, you want to know the value currently in effect."



I have found this useful for changing the error reporting levels for a few specific pages while testing. I turn on all error_reporting while testing, but for a few pages I want to turn off notices. So, I put this at the top of the page:



error_reporting(8183);



and this at the bottom:



error_reporting(get_cfg_var('error_reporting'));



to put it back to whatever default I had at the time.

get_cfg_var returns the value from php.ini directly,while the ini_get returns   the runtime config value. I have tried it on PHP 5.1.6

ini_get() return the current value of the configuration option.

But the get_cfg_var() always get the value from config file, php.ini.
