PHP Bug Type: mbstring related
Bug description: mbstring function overloading - local value ignored
Description:
------------
I got a new error message in PHP 5.2 when using mb_strstr() with an empty
string as haystack. So I wrote a testfile to compare the behaviour of
strstr() with mb_strstr().
Although mbstring function overloading is not enabled and the phpinfo()
output (in the same file, so there are no more changes via .htaccess) says
that all mbstring settings are the default settings, strstr() is overloaded
with mb_strstr().
phpinfo output:
---
Multibyte Support enabled
Multibyte string engine libmbfl
Multibyte (japanese) regex support enabled
Multibyte regex (oniguruma) version 4.4.4
Multibyte regex (oniguruma) backtrack check On
mbstring extension makes use of "streamable kanji code filter and
converter", which is distributed under the GNU Lesser General Public
License version 2.1.
Directive Local Value Master Value

Reproduce code:
---------------
<?php
//phpinfo();
strstr('', ',');
mb_strstr('', ',');
?>
Expected result:
----------------
Warning: strstr() [function.strstr]: Empty haystack in
W:\www\strstr\strstr.php on line 3
Warning: mb_strstr() [function.mb-strstr]: Empty haystack in
W:\www\strstr\strstr.php on line 4
Actual result:
--------------
Warning: mb_strstr() [function.mb-strstr]: Empty haystack in
W:\www\strstr\strstr.php on line 3
Warning: mb_strstr() [function.mb-strstr]: Empty haystack in
W:\www\strstr\strstr.php on line 4
