PHP's substr() function does exactly what you need:

Code below is from PHP Manual
(http://uk.php.net/manual/en/function.substr.php)

<?
$rest = substr("abcdef", 1); // returns "bcdef"
$rest = substr("abcdef", 1, 3); // returns "bcd"
$rest = substr("abcdef", 0, 4); // returns "abcd"
$rest = substr("abcdef", 0, 8); // returns "abcdef"
?>

It seems easy enough to get working.
