Description:
eregi() produce random errors like function.mb-eregi: mbregex compile
err: premature end of regular expression in when used with special
chars like accents.
N.B. On the web you can found a lot of reports of this issue. Some post
suggests forcing mbstring.func_overload = 0 but it doesn't work for me.
If Apache1 is restarted the error doesn't come anymore before an amount
of time and request.

#27421 [Com]: mbstring.func_overload set in .htaccess becomes global
ID: 27421 Comment by: lip at lip dot net dot ua Reported By: php at strategma dot bg Status: No Feedback Bug Type: mbstring related Operating System: Slackware 9.1 kernel: 2.4.22 PHP Version: 4.3.4 New Comment: I also have this problem. PHP 5.2.5 Apache/2.2.8 If I use mbstring.func_overload in .htaccess other virtualhosts not work For example: VirtualHost *:80 DocumentRoot /var/www/phpmyadmin AddHandler cgi-script .cgi AddHandler cgi-script .pl ServerName n.com.net /VirtualHost VirtualHost *:80 DocumentRoot /var/www/db ServerName db.net /VirtualHost in /var/www/db/.htaccess php_value mbstring.func_overload 6 In this situation phpmyadmin doesnt work when I refresh few times db.net Previous Comments: [2008-01-17 13:35:30] mihau at great dot net dot pl I'm still experiencing this bug. On apache 2.0.59 with php 5.2.4, as well as php 4.4.x. It looks like mbstring.func_overload setting in .htaccess affects other virtualhosts and directories. I've tried with these in httpd.conf: IfModule prefork.c MaxRequestsPerChild 10 /IfModule It works as expected for site A until I enter site B with mbstring.func_overload in .htaccess. Site B works as expected. Then i come back to site A and see unexpected results. I hit refresh few times and results back to normal. It looks like one request affects all other requests for specified child. When apache kill it after MaxRequestPerChild and spawn new child everything is working fine, until site B is requested. Is this bug somehow related to #43677? With one exception: ini_get(mbstring.func_overload) returns correct values - I mean values from config files. [2007-01-18 09:29:39] info at bert-jan dot com I've tried it on another server running Debian unstable with PHP 5.2.0-8 on Apache 2.2.3 both installed with apt-get and the same issue is reproducible here too. [2007-01-17 21:57:23] info at bert-jan dot com FYI: I'm running Slamd64 (Slackware x86-64) with Apache and PHP installed from source. Apache: ./configure \ --enable-ssl \ --with-ssl \ --enable-proxy \ --enable-proxy-connect \ --enable-proxy-ftp \ --enable-proxy-http \ --enable-rewrite \ --enable-deflate \ --enable-so \ PHP: ./configure \ --with-apxs2=/usr/local/apache2/bin/apxs \ --with-mysql=/usr/local/mysql/ \ --with-zlib \ --with-gd \ --with-jpeg-dir \ --with-png-dir \ --with-freetype-dir \ --enable-ftp \ --with-bz2 \ --with-gzip \ --with-openssl \ --enable-shmop \ --enable-posix \ --enable-pcntl \ --enable-sysvsem \ --enable-sysvshm \ --enable-iconv \ --with-mysqli=/usr/local/mysql/bin/mysql_config \ --enable-mbstring \ --enable-shmop \ --enable-soap \ --enable-memory-limit [2007-01-17 21:41:53] info at bert-jan dot com I'm having this exact same issue on PHP 5.1.6 on Apache 2.0.59. Putting the mbstring.* settings in the VirtualHost-directive or in .htaccess doesn't seem to make a difference. The settings are 'leaked' to other vhosts who start to randomly malfunction and report errors like Warning: mb_strrpos() [function.mb-strrpos]: Unknown encoding 6 in /home/bertjan/public_html/functions.php on line 307 As stated in the other comments, the erroneous behaviour isn't consistent. Sometimes it works but more often it doesn't. The trouble is quite evident in e.g. Squirrelmail or phpMyAdmin. [2006-11-17 15:02:35] christophe at saout dot de I'm still seing a similar problem in PHP 4.4.4. The site has globally turned on mbstring.func_overload in php.ini. When turning it off in a .htaccess for a specific directory, the behaviour experienced by the scripts in that directory becomes random. Sometimes it works as expected (especially after a fresh start of apache), but most of the time the script is using the overloaded mbstring functions e.g. for substr, even though ini_get(mbstring.func_overload) returns 0. It looks like the save/restore in the mbstring module somehow gets confused and leaks overloaded functions between apache requests. Assuming this is a variant of the bug experienced by the original bug author, I'm posting this here and requesting a re-opening. The remainder of the comments for this report are too long.
