I have been working on a lot of stuff but I have not had time to work much on tutorials lately.

<?php

//Recursion
// a recursive function is one that calls itself
function reverse_r($str) {
if (strlen($str)>0) {
reverse_r(substr($str, 1));
}
echo substr($str, 0, 1);
return;
}

function reverse_i($str) {
for ($i=1; $i echo substr($str, -$i, 1);
}
return;
}

reverse_r('Hello');

reverse_i('Hello');
?>
