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

I'd suggest using $_POST and $_GET explicitly.

Using $_REQUEST should be unnecessary with proper site design anyway, and it comes with some downsides like leaving you open to easier CSRF/XSS attacks and other silliness that comes from storing data in the URL.

The speed difference should be minimal either way.
