    $file_name=ereg_replace('[^a-z0-9]','',$file_name);
    PHP:
    [a-z0-9]:matches characters from a to z or from 0 to 9,
    [^a-z0-9]:matches characters that aren't from a to z nor from 0 to 9, the ereg_replace function removes this characters, more precisely, it changes them to '' (empty string).
