1 to 1000 in PHP With No Conditionals or Loops

Inspired by this post (a puzzle challenge asking if you could think of a way to print from 1-1000 in C++ with no conditionals or loops)

I wondered if I could think of a hack to do it in PHP… here’s my hack!

<?php
   sleep(1);
   $i = ++$_GET['i'];
   $go[1000] = 'http://google.com?';
   header("Location: {$go[$i]}/?i=$i");
?>

It’s a PHP script (index.php) running from the root of a server with warnings switched off.

As an added bonus you need to watch http live headers to see the “print” out 😉

(Note: It’ won’t work in most modern browsers as they tend to have a limit of 20 redirects. Meh. That’s just a technicality.)
