-Summary: mbstring function overloading - done although not
activated
Reported By: christoph at ziegenberg dot de
Status: Open
Bug Type: mbstring related
Operating System: Win XP SP 2
PHP Version: 5.2.0
New Comment:
The value returned by ini_get() is correct (also the phpinfo() output),
but the behavior is wrong... I tested several other ini settings, but
the error seems to occur only with the mbstring function overloading.

Oh... I got the reason for it... really bad bug, might be critical and
influence other ini setting to:
1) run the script - it works. you get the error message for mb_strstr()
only:
Warning: mb_strstr() [function.mb-strstr]: Empty haystack in
W:\www\strstr\strstr.php on line 4
2) run a script in another directory with mbstring function overloading
activate* - the result is as expected:
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
3) now run the first script (NOT in the created directory!) and you get
the same error messages!
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
So the overloading setting is activated for the wrong directory!
* via .htaccess:
php_value mbstring.func_overload 6

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
mbstring.detect_order no value no value
mbstring.encoding_translation Off Off
mbstring.func_overload 0 0
mbstring.http_input pass pass
mbstring.http_output pass pass
mbstring.internal_encoding no value no value
mbstring.language neutral neutral
mbstring.strict_detection Off Off
mbstring.substitute_character no value no 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
