get_cfg_var

(PHP 3, PHP 4 , PHP 5)

get_cfg_var -- Gets the value of a PHP configuration option

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:





<?php


error_reporting(8183);


?>





and this at the bottom:





<?php


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





[EDIT by danbrown AT php DOT net: The author of this note means that ini_get() will return values set by ini_set(), .htaccess, a local php.ini file, and other functions at runtime.  Conversely, get_cfg_var() will return strictly the server php.ini.]
