 New Comment:

The default character encoding, which your calls to mb_strcut() will be using, changed to be UTF-8
in PHP 5.6.

Description:
------------
I used ord() in combination with mb_strcut() to obtain the byte values of a multibyte char utf-8
encoded.  This used to work in PHP 5.4.8 - 5.5.29.  But in PHP5.6-PHP7.00rc3 it doesn't work
any more :(

Test script:
---------------
<?php 


$str = "♥"; // 3 byte values per above

var_dump( ord(mb_strcut($str, 0, 1) )); 
var_dump( ord(mb_strcut($str, 1, 1) )); 
var_dump( ord(mb_strcut($str, 2, 1) ));

see live code: https://3v4l.org/OoFus

Expected result:
----------------
I expected the var dumps to produce decimal results as follows:

 226 
 153
 165

Actual result:
--------------
0
0
0
