From manual page: http://www.php.net/function.base64-decode#Return Values
---

If a string to decode has wrong bytes at the end of the string, which normally ends with "=", then base64_decode() returns a wrong result of decode.


Test script:
---------------
<?php
$a = "qwertyui";
$aa = base64_encode($a);
echo base64_decode($aa.'\\0');
?>

Expected result:
----------------
qwertyui

Actual result:
--------------
qwertyui4
