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