#16113 [Opn->Bgs]: Circulaire includes makes Apache hang.

ID: 16113 Updated by: iliaa@php.net Reported By: tozz@embrace.selwerd.nl -Status: Open +Status: Bogus Bug Type: Scripting Engine problem Operating System: Any? (Mine: Linux 2.4.13) PHP Version: 4.1.2 New Comment: Sorry, but the bug system is not the appropriate forum for asking support questions. Your problem does not imply a bug in PHP itself. For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php Thank you for your interest in PHP. Just like any other programming/scripiting language, PHP can be used to cause trouble. To avoid this kind of problems use include_once or require_once.

The problem? In short, i reproduced the problem by making 2 files: file1.php: <? include("http://host.name/file2.php"); ?> file2.php <? include("http://host.name/file1.php"); ?> When you open http://host.name/file1.php you will see an enormous amount of Apache childs. And apache hangs (it does not respond to new requests!). I know its the user his fault, but when you have a very complicated website this might happen because of bugs in your scripts. Because of this my Apache webserver died and I had to restart Apache to make it work again. Perhaps its a good idea to add somekind of check to prevent things like this? ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=16113&edit=1
