<?php
/* Prototype : proto int strspn(string str, string mask [, int start [, int len]])
* Description: Finds length of initial segment consisting entirely of characters found in mask.
If start or/and length is provided works like strspn(substr($s,$start,$len),$good_chars)
* Source code: ext/standard/string.c
* Alias to functions: none
