  19  * Smarty plugin
  20  * Type: modifier
  21  * Name: substring
  22  * Version: 0.1
  23  * Date: 2006-16-02
  24  * Author: Thorsten Albrecht <thor_REMOVE.THIS_@wolke7.net>
  25  * Purpose: "substring" allows you to retrieve a small part (substring) of a string.
  26  * Notes: The substring is specified by giving the start  position and the length.
  27  * Unlike the original function substr() in PHP the position of the characters
  28  * in the string starts at 1 (not at 0 as usual in php).
  29  * Example smarty code:
  30  *   {$my_string|substring:2:4}
  31  *   returns substring from character 2 until character 6
  32  * @link based on substr(): http://www.zend.com/manual/function.substr.php
  33  * @param string $string
  34  * @param int $position
  35  *   startposition of the substring, beginning with 0
  36  * @param int $length
  37  *   length of substring
  38  * @return string
