I need to figure out a way to extract only numberic data from one field into another.

original data:
test2345.gif


results I would like:
2345

please help! I have spent way to much time trying to figure this out.

Something like this should work:

[code]$s = "test2345.gif";

function getnumbers($str) {
    $ret = "";
    for ($i = 0; $i <= strlen($str); $i++) {
        if (is_numeric($str{$i})) {
            $ret .= $str{$i};
        }
    }
    return $ret;
}

echo getnumbers($s);[/code]
