When not working within my framework (which facilitates this
automatically), I tend to have a function for each just to save time:

function g($key){
   return isset($_GET[$key]) ? $_GET[$key] : null;
}

function p($key){
   return isset($_POST[$key]) ? $_POST[$key] : null;
}

function c($key){
   return isset($_COOKIE[$key]) ? $_COOKIE[$key] : null;
}

function s($key, $val = null){
   !isset($_SESSION) && session_start();

   if ($val === null) {
      return isset($_SESSION[$key]) ? $_SESSION[$key] : null;
   } else {
      return $_SESSION[$key] = $val;
   }
}

Then, you can just write:

$first_name = s('first_name', p('first_name'));
