It seems that this function doesn't work on Unix Operating Systems. Use ini_get(); instead. Just a warning to unsuspecting scripters.
get_cfg_var
(PHP 4, PHP 5)
get_cfg_var — Obtiene el valor de una opción de configuración de PHP
Descripción
Obtiene el valor de una opcion de configuración de PHP.
Esta función no devolverá información de configuración definida cuando PHP fuera compilado, ni leerá desde un archivo de configuración de Apache (usando las directivas php3_configuration_option).
Para chequear si el sistema está usando un archivo de configuración, intente recuperar el valor del parámetro de configuración cfg_file_path. Si éste se encuentra disponible, quiere decir que un archivo de configuración está siendo usado.
Lista de parámetros
- opcion
-
El nombre de la opción de configuración.
Valores retornados
Devuelve el valor actual de la opción de configuración de PHP indicada por opcion , o FALSE si ocurre un error.

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.

In PHP4.3.0£¬I test this in WindowXP£¬I found the Get_Cfg_Var() and ini_get() is same return the current value of the configuration,not from config file php.ini NOW!!!

ini_get() return the current value of the configuration option.
But the get_cfg_var() always get the value from config file, php.ini.
This is the test code:
ini_set('sendmail_from', 'verdana@263.net');
echo '<br /> <br />';
echo '<br /> Current Value:';
var_dump(ini_get('sendmail_from'));
echo '<br /> Value in cfg file:';
var_dump(get_cfg_var('sendmail_from'));

If you are using PHP 4.0+ (and if not, why not!) use ini_get().
This will return the local value - even if you've set it via apache in http.conf as I did during testing.

As implemented, this function is an odd wart--it calls cfg_get_string, which returns the value originally set in the config file, if any.
Unfortunately, you almost never want to know the original value in the config file. Instead, you want to know the value currently in effect. (These two values can be different if you have no php.ini file, or if you're setting options in httpd.conf or .htaccess files.)
To get the current value of a configuration option you should use ini_get() instead
