PHP version: 5.2.0
PHP Bug Type: mbstring related
Bug description: mb_strstr() behaviour differs from strstr()
Description:
------------
as described in the more important bug #39361 i compared strstr() and
mb_strstr().
mb_strstr() produces the following error when using an empty haystack:
Warning: mb_strstr() [function.mb-strstr]:
Empty haystack in X on line Y
but strstr() doesn't.
Reproduce code:
---------------
<?php
strstr('', ',');
mb_strstr('', ',');
?>
Expected result:
----------------
no error message - because haystack does not contain needle, so the
function should return false, as described in the documentation. the
different behavior produces a lot of errors when using function
overloading (although i know using it is not a good idea... ;).
Actual result:
--------------
Warning: mb_strstr() [function.mb-strstr]: Empty haystack in X on line Y
