get_cfg_var — Retourne la valeur d'une option de PHP
Retourne la valeur de l'option option de configuration PHP.
get_cfg_var() ne retourne pas les options qui ont été choisies lors de la compilation de PHP, ni ne lit dans le fichier de configuration d'Apache.
Pour vérifier si le système utilise le fichier de configuration, essayez de lire la valeur de cfg_file_path. Si cette valeur est disponible, alors le fichier de configuration est utilisé.
optionLe nom de l'option de configuration.

option ou bien false si une erreur survient.
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.]settings with the value of 'yes' will be returned as '1'.
<?php
//#my ini file
//A = 1
//B = any-thing
//C = yes
//D = /some/path/file
get_cfg_var('A') // returns '1'
get_cfg_var('B') // returns 'any-thing'
get_cfg_var('C') // returns '1', wait, why?
get_cfg_var('D') // returns '/some/path/file'
?>
I had my setting = yes and then checked it as ==="yes" for epic fail.Boolean-like values are evaluated as follows: "true", "on", "yes" evaluate to "1" (string 1), while "false", "off", "no" evaluate to "" (empty string).keep in mind get_cfg_var() returns a string(1) '1' for the value: On
<?php
//in php.ini
//A = On
$A1 = get_cfg_var("A") === "On";
$A2 = get_cfg_var("A") === 1;
$A3 = get_cfg_var("A") === "1";
//$A1 is false
//$A2 is false
//$A3 is true
?>The difference between ini_get() and get_cfg_var() is as follows:
@) ini_get(): returns the current value in .htaccess or as defined in PHP_INI_USER or PHP_INI_PERDIR
@) get_cfg_var: returns the values defined in the php.ini
