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          


        

Answer 1

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

Use that because it is safer and it won't make noticeable speed difference
