Description:
------------
Changing internal character encoding during script
execution apparently affects mbstring function overloading:
strlen() returns the length of the string based on current
internal encoding although function overloading is disabled
(either through php.ini, vhost and/or .htaccess settings.)
On apache 1.3 startup or graceful restart, script may run
as expected but repeated requests would inevitably trigger
the bug -- on my server setup, MediaWiki cannot run
reliably because of this weird behavior :-/
The bug is not triggered when I do run this script under
other SAPIs such as CLI or FastCGI.
./configure --with-apxs=/usr/local/apache/bin/apxs
--with-mysql=/usr/local --with-openssl=/usr/local/apache
--with-gd=/usr/local --with-zlib --with-bz2 --with-xml
--with-freetype-dir=/usr/local --with-ttf --with-imap
--with-curl
--with-jpeg-dir=/usr/local --with-png-dir=/usr/local
--with-readline=/usr/local --prefix=/usr/local/apache
--with-config-file-path=/usr/local/apache/etc
--enable-mbstring
--enable-mbregex --enable-zend-multibyte
; configure line
Reproduce code:
---------------
http://www.diptyque.net/bugs/mbinfo.php
; running PHP 4.4 as an apache module
; display charset is set to UTF-8
; when internal encoding is set to UTF-8,
; strlen() returns the wrong character count
; (e.g. 18 instead of 19)

; source code
Expected result:
----------------
string(10) "ISO-8859-1"
string(10) "ISO-8859-1"
string(1) "0"
string(19) "Méthodes de codage"
int(19)
--
bool(true)
string(5) "UTF-8"
string(10) "ISO-8859-1"
string(1) "0"
string(19) "Méthodes de codage"
int(18)
--
bool(true)
string(10) "ISO-8859-1"
string(10) "ISO-8859-1"
string(1) "0"
string(19) "Méthodes de codage"
Actual result:
--------------
string(10) "ISO-8859-1"
string(10) "ISO-8859-1"
string(1) "0"
string(19) "Méthodes de codage"
int(19)
--
bool(true)
string(5) "UTF-8"
string(10) "ISO-8859-1"
string(1) "0"
string(19) "Méthodes de codage"
int(19)
--
bool(true)
string(10) "ISO-8859-1"
string(10) "ISO-8859-1"
string(1) "0"
string(19) "Méthodes de codage"
