Among $_REQUEST, $_GET and $_POST which one is the fastest?

Question

Which of these code will be faster?

$temp = $_REQUEST[\'s\'];

or

if (isset($_GET[\'s\'])) {
  $temp = $_GET[\'s\'];
}
else

Don't worry. But you should still use the second solution (plus an extra check for none of those variables existing), because there are security issues with $_REQUEST (since $_GET and $_POST aren't the only sources for that array).

There was a post about the problems with $_REQUEST yesterday, I believe. Let me go find it.
