To the last poster, regarding the speed tests:
<?php
$a = str_repeat('text', 100);
$b = $a;
$c =& $a;
// $c == $b == $a
// But you assigned a different value within the functions:
$len = strlen($a); // $len != $a
?>
I was bemused; how could the processing times of the functions/no-functions tests be compared in
this way? And calling the strlen() function within each iteration of the loop must take more time
anyway?
