I wouldn't recommend ereg() unless you have some complex pattern matching to
do. If you're always looking for the same string, in the same spot,then just
use substr(). Now...if you want to match _any_ 3 numbers, etc, then that's
when ereg() comes into play.

eregi() is the go... whilst the documentation is pretty thin on the actual
expressions, '^' checks for the pattern at the begining of a string.
<?
if(eregi('^324', $string)) {
//
// it did begin with "324"
//
} else {
//
// it didn't
//
}
?>
