#19049 [Com]: Variables go missing suddenly (not register_globals related!)

ID: 19049 Comment by: proton@fancreations.com Reported By: proton@fancreations.com Status: Feedback Bug Type: Variables related Operating System: Windows XP Home PHP Version: 4.3.0-dev New Comment: It seems that this bug has been fixed in PHP 4.2.3, cause my code now works fine again. I think it has to do with this entry in the 4.2.3 changelog: - Fixed several bugs in the multithreaded version that could cause random parse errors, especially on machines with multiple CPUs. (Zeev, Zend Engine) Sniper, thanks anyway for your time and help!

I will try to remove parts of the code which are not used next week and then create a small test script, but I'm a little busy right now. ------------------------------------------------------------------------ [2002-08-23 07:45:01] sniper@php.net Can you give us a complete but short script? (that one function alone is not one :) ------------------------------------------------------------------------ [2002-08-23 03:51:04] proton@fancreations.com With php4-win32-latest I still have the same problem, variables that go undefined suddenly... ------------------------------------------------------------------------ [2002-08-22 17:21:32] sniper@php.net Please try using this CVS snapshot: http://snaps.php.net/php4-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-latest.zip There were some fixes lately which might be related. ------------------------------------------------------------------------ [2002-08-22 11:02:48] proton@fancreations.com I have this function I've been using to find a bug in my script, but that now appears to be a bug in PHP itself: function debug($msg) { echo '<b>DEBUG</b>: ' . $msg . '<br/>'; } I have this function on a page with a form on it. When I call this function when the form is not submitted yet, everything goes fine, but when I call it when I have submitted the form, it goes fine a couple of times but then it gives me this message, saying that the variable is undefined: Notice: Undefined variable: msg in f:\website\public_html\test\form.php on line 51 Line 51 is the "echo '<b>'..." line in the function above. I get simillar strange behaviour when I create a new object and then in the object's constructor I access $this and it also gives me an undefined variable error. I get this behaviour with both Apache 2 (2.0.40) and Apache 1 (1.3.26), with PHP versions 4.2.0 and 4.2.2. I haven't tested it on any other versions, but I think it will behave the same. Sometimes Apache 2 crashes on this, other times it would display the errors. After having this a couple of times, my computer even restarts by itself for some reason! Apache 1 always displays the error message. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=19049&edit=1
