Thanks for your time and explanation. Close this ticket please. ------------------------------------------------------------------------ [2012-06-25 09:50:08] laruence@php.net I have discussed with ekneuss about this FR for a bit. thanks to ekneuss, we found there are some limits, 1. since PHP is a dynamic language, then for $obj->function, we can not determine what $obj is, so if we want to implement this FR, we have to do the check at run-time. 2. there is another question while for following codes: function bar($i) { if ($i == 42) { $obj->someFuncThrowException(); } } so, should we trigger WARNING all the times? 3. unlesss ZEND_CATCH is executed, we have no idea what type of exception will be caught by catch, so, if we implement a whole exception type check, we will need: exception autoload, and catch statements analyse , which will bring a obvious performance slow down.. anyway, I can do more research later , thanks :) ------------------------------------------------------------------------ [2012-06-24 19:23:39] normandiggs at gmail dot com Description: ------------ Please, add Checked Exceptions to PHP (from Java). Test script: --------------- <?php Class Example { public function SomeFunction() throws \PDOException, \Some\Interface { //... } } Class Check { protected function CheckItWrong() { $Example = new Example; // please, generate "warning" here, because "try-catch" // with necessary types wasn't declared around call. $Example->SomeFunction(); } } ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=62404&edit=1
