note 130175 added to function.set-error-handler

Usually, this method is not called in a loop, but if it is, there is one thing that may be EXTREMELY important to think of, and that is to run restore_error_handler() once for each call to set_error_handler. Otherwise, you will have a memory leak. Every time set an error handler, even if it's identical to the previous one, you're pushing the previous one to a stack. We recently had a big crash due to this, and we had a very hard time finding out what the problem was. There was no error message or anything. Just a big crash. ---- Server IP: 45.112.84.4 Probable Submitter: 80.90.5.137 (proxied: 213.115.8.221) ---- Manual Page -- https://php.net/manual/en/function.set-error-handler.php Edit -- https://main.php.net/note/edit/130175 Del: integrated -- https://main.php.net/note/delete/130175/integrated Del: useless -- https://main.php.net/note/delete/130175/useless Del: bad code -- https://main.php.net/note/delete/130175/bad+code Del: spam -- https://main.php.net/note/delete/130175/spam Del: non-english -- https://main.php.net/note/delete/130175/non-english Del: in docs -- https://main.php.net/note/delete/130175/in+docs Del: other reasons-- https://main.php.net/note/delete/130175 Reject -- https://main.php.net/note/reject/130175 Search -- https://main.php.net/manage/user-notes.php
