#31578 [NEW]: Type hinting fata error

From: mgkimsal at conduit dot com Operating system: all PHP version: 5.0.2 PHP Bug Type: *General Issues Bug description: Type hinting fata error 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 bug report at http://bugs.php.net/?id=31578&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=31578&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=31578&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=31578&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=31578&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=31578&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=31578&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=31578&r=needscript Try newer version: http://bugs.php.net/fix.php?id=31578&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=31578&r=support Expected behavior: http://bugs.php.net/fix.php?id=31578&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=31578&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=31578&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=31578&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=31578&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=31578&r=dst IIS Stability: http://bugs.php.net/fix.php?id=31578&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=31578&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=31578&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=31578&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=31578&r=mysqlcfg
