note 7695 modified in get_cfg_var by hholzgra

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 http://www.php.net/manual/function.get-cfg-var.php
