I think a regex would be most appropriate here:
<?php
$my_string = "mmm444";
$my_integer = intval(eregi_replace("[a-z]", "", $my_string));
print $my_integer;
?>
This removes all letters and takes the int value. In perl you can remove
everything that's NOT a digit but I didn't figure that out in PHP yet... this
should do for now.
