get_cfg_var

(PHP 3, PHP 4, PHP 5)

get_cfg_var -- Obtiene el valor de una opciÃ³n de configuraciÃ³n de PHP

DescripciÃ³n

string get_cfg_var ( string nombre_var )

Devuelve el valor actual de la opciÃ³n de configuraciÃ³n de PHP indicada por nombre_var, o FALSE si ocurre un error.

No devolverÃ¡ informaciÃ³n de configuraciÃ³n definida cuando PHP fuera compilado, ni leer desde un archivo de configuraciÃ³n de Apache (usando las directivas php3_configuration_option).

Para chequear si el sistema estÃ¡ usando un archivo de configuraciÃ³n, intente recuperar el valor del parÃ¡metro de configuraciÃ³n cfg_file_path. Si Ã©ste se encuentra disponible, quiere decir que un archivo de configuraciÃ³n estÃ¡ siendo usado.

Vea tambiÃ©n ini_get().

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
