ID: 38577 User updated by: php at diptyque dot net Reported By: php at diptyque dot net Status: Open Bug Type: mbstring related Operating System: FreeBSD 4.4 PHP Version: 4.4.4 New Comment:
Oops, my mistake. You should swap Expected and Actual results. Actual result is int(18) !? Expected result is int(19). Previous Comments: ------------------------------------------------------------------------ [2006-08-24 12:28:30] php at diptyque dot net Granted I could not reproduce either this bug using a WAMP setup but did you follow the hyperlink I gave on my FreeBSD-based server, where you can consistently replicate this bug on each GET request? ------------------------------------------------------------------------ [2006-08-24 11:03:09] [EMAIL PROTECTED] Can't reproduce. I get int(19) in all cases. ------------------------------------------------------------------------ [2006-08-24 10:17:16] php at diptyque dot net 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) http://www.diptyque.net/bugs/mbinfo.phps ; 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" ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=38577&edit=1
