--TEST--
Test strcspn() function : usage variations - with heredoc strings, varying mask & default start and len args
--FILE--

* Description: Finds length of initial segment consisting entirely of characters not found in mask.
If start or/and length is provided works like strcspn(substr($s,$start,$len),$bad_chars)
* Source code: ext/standard/string.c
* Alias to functions: none
