#31578 [Opn->WFx]: Type hinting fata error

ID: 31578 Updated by: derick@php.net Reported By: mgkimsal at conduit dot com -Status: Open +Status: Wont fix -Bug Type: *General Issues +Bug Type: Feature/Change Request Operating System: all PHP Version: 5.0.2 New Comment: We decided in the past that this should be a fatal error, and not catchable. If you want to make sure your objects are the correct class, you have to test that before you call the method with the type hint. Previous Comments: ------------------------------------------------------------------------ [2005-01-17 02:25:17] mgkimsal at conduit dot com Description: ------------ http://us3.php.net/manual/en/language.oop5.typehinting.php states that "Failing to satisfy the type hint results in a fatal error." This seems relatively useless compared to having PHP5 throw an exception. This would make it a recoverable situation that could be handled gracefully rather than yet another fatal error which PHP can't deal with. http://bugs.php.net/bug.php?id=28001&edit=2 had a response from Derick stating that someone should just write their own custom error handler to catch this and deal with it, but it's a fatal error - my php5.0.2 can not catch fatal errors, and I'm not seeing anything in the docs that says we should be able to handle fatal errors with user-defined code. I *DID* see an example file that caught a FATAL error *when it was invoked by trigger_error()* but it doesn't work in the code below. Reproduce code: --------------- <?php set_error_handler("myfunc"); error_reporting(E_ALL); function myfunc($errno, $errstr, $errfile, $errline) { echo "err=$errono"; print_r(debug_backtrace()); } class bar { } class foo { function me(bar $b) { print_r($b); } } $b = new bar; $f = new foo(); $f->me("fff"); ?> Expected result: ---------------- I would expect a backtrace() dump on the screen. Actual result: -------------- PHP Fatal error: Argument 1 must be an object of class bar in /var/www/html/v5/er.php on line 12 Fatal error: Argument 1 must be an object of class bar in /var/www/html/v5/er.php on line 12 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=31578&edit=1
