note 80884 added to function.set-error-handler

BE CAREFUL! System generated exceptions are actually E_WARNINGS first before they are exceptions. Tested on 5.2.3-5.2.5 Order of preference for exceptions generated by PHP (not user-land throw new Exception();} 1. set_error_handler(); 2. set_exception_handler(); 3. try/catch block in the code. So, your custom error handler has to magically decide if any old E_WARNING is actually an exception or not so it can return false for that one warning so it can be converted into a real exception and handed off to your try/catch block. This seriously cripples try/catch functionality around system generated exceptions (like new DateTimeZone('zzzzzz');). ---- Server IP: 208.69.120.35 Probable Submitter: 67.149.236.232 ---- Manual Page -- http://www.php.net/manual/en/function.set-error-handler.php Edit -- https://master.php.net/note/edit/80884 Del: integrated -- https://master.php.net/note/delete/80884/integrated Del: useless -- https://master.php.net/note/delete/80884/useless Del: bad code -- https://master.php.net/note/delete/80884/bad+code Del: spam -- https://master.php.net/note/delete/80884/spam Del: non-english -- https://master.php.net/note/delete/80884/non-english Del: in docs -- https://master.php.net/note/delete/80884/in+docs Del: other reasons-- https://master.php.net/note/delete/80884 Reject -- https://master.php.net/note/reject/80884 Search -- https://master.php.net/manage/user-notes.php
