URL Shortner

Posted Fri, 30/04/2010 - 4:51pm by DrupalD

This CodeLet generates and returns a short url when providing a long url. This is useful especially when you have a really long url and you want paste in forums, discussion boards, emails etc. You can even bookmark this short url. Here, only url shortning algorithm added. You can build other features around it. This is a very primary algorithm and you can improve it further.

<?php
  /**

*/
function _get_short_url() {
  $sn__rand = mt_rand(100000000000, 999999999999);
  $am__id = str_split($sn__rand, 3);
  for ($i = 0; $i < count($am__id); $i++) {
    if (is_numeric($am__id[$i]) && $am__id > 0) {
      if ($am__id[$i] < 65) {
        if ($am__id[$i] >= 48 && $am__id[$i] <= 57) {
          $am__id[$i] = chr($am__id[$i]);
        }
      }
      else if ($am__id[$i] >= 65 && $am__id[$i] <= 90 && $am__id[$i] >= 97 && $am__id[$i] <= 122) {
        $am__id[$i] = chr($am__id[$i]); 
      }
      else if ($am__id[$i] > 122) {
        $am__id[$i] = chr(65 - $am__id[$i]); 
      }
      $am__char[] = $am__id[$i];
    }
  }
  return implode("", $am__char);
} 
?>
