variables_order string

Sets the order of the EGPCS (Environment, Get, Post, Cookie, and Server) variable parsing. For example, if variables_order is set to “SP” then PHP will create the superglobals $_SERVER and $_POST, but not create $_ENV, $_GET, and $_COOKIE. Setting to “” means no superglobals will be set.

If the deprecated register_globals directive is on, then variables_order also configures the order the ENV, GET, POST, COOKIE and SERVER variables are populated in global scope. So for example if variables_order is set to “EGPCS”, register_globals is enabled, and both $_GET[‘action’] and $_POST[‘action’] are set, then $action will contain the value of $_POST[‘action’] as P comes after G in our example directive value.

Warning

In both the CGI and FastCGI SAPIs, $_SERVER is also populated by values from the environment; S is always equivalent to ES regardless of the placement of E elsewhere in this directive.

Note:

The content and order of $_REQUEST is also affected by this directive.
