Legacy PHP: str_split function

This stems from 2003 when str_split() did not exist in PHP and was just being added. It showed how to implement a compatible function if your host didn’t have a newer version of PHP.

if (!function_exists('str_split')) {
  Function str_split($string, $chunksize=1) {
    preg_match_all('/('.str_repeat('.', $chunksize).')/Us', $string, $matches);
    return $matches[1];
  }
}

Note: This page is legacy – you won’t ever use this now. PHP has had str_split() for 15 years.
