--TEST--
Test strspn() function : usage variations - with heredoc strings, varying start and default len args

<?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
