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:
I forgot to mention that mbstring.func_overload is enabled on a per-vhost basis for some other web sites I'm hosting on this platform. Previous Comments: ------------------------------------------------------------------------ [2006-08-24 16:20:24] php at diptyque dot net Agreed but I'm not making things up, you know. Something is obviously wrong on my Apache 1.3.34 setup. Could this be a conflict with some extension or Apache module? Of course, no opcode cache is running. Any tip welcome. This weird behavior has been plaguing me for 2 months now and rebuilding PHP doesn't seem to help. I wrote a second test case which demonstrates that function overloading is effectively taking place sporadically while running under apache SAPI -- strlen() may accept the optional encoding argument (!?) as shown in the script output below. http://www.diptyque.net/bugs/mbinfo2.php http://www.diptyque.net/bugs/mbinfo2.phps ; source code =begin [diptyque] % GET http://www.diptyque.net/bugs/mbinfo2.php <pre>int(72208) 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) int(19) -- bool(true) string(10) "ISO-8859-1" string(10) "ISO-8859-1" string(1) "0" string(19) "Méthodes de codage" int(19) int(18) </pre> =end If I do run the same script through PHP CLI or FastCGI, I get the following expected warnings: PHP Warning: Wrong parameter count for strlen() in /path/to/htdocs/bugs/mbinfo2.php on line 17 PHP Warning: Wrong parameter count for strlen() in /path/to/htdocs/bugs/mbinfo2.php on line 25 ------------------------------------------------------------------------ [2006-08-24 15:15:31] [EMAIL PROTECTED] Please try with minimal configuration (like ./configure --enable-mbstring) and PHP CLI. If you're still able to reproduce it, you're likely to be the only person who can help you, since I really doubt anyone else can do it. ------------------------------------------------------------------------ [2006-08-24 15:04:03] php at diptyque dot net I moved mbstring function overload initial setting (6) from my php.ini to specific virtual hosts configuration sections but to no avail. It would seem that some Apache processes get it right while others get it wrong (!) This is quite weird -- for example, process #58902 returns int(18) while #58914 returns int(19).

You should swap Expected and Actual results. Actual result is int(18) !? Expected result is int(19). ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
