#42439 [Bgs->Opn]: Derivating a method in a class that implements an interface that declares it

ID: 42439 User updated by: romain dot tartiere at healthgrid dot org Reported By: romain dot tartiere at healthgrid dot org -Status: Bogus +Status: Open Bug Type: Class/Object related Operating System: GNU/Linux PHP Version: 5.2.3 New Comment: Reopen bug since it seems to have been closed too quickly. Previous Comments: ------------------------------------------------------------------------ [2007-08-27 12:43:04] romain dot tartiere at healthgrid dot org Thank you for your personalised answer and taking time to read and understand my bug report. This is obviously a bug. A class method prototype does not have to comply with an interface method prototype if this class does not implements this interface. This is a regression: everything was OK with PHP 5.0. Thank you to take this bug report into account. ------------------------------------------------------------------------ [2007-08-27 10:24:59] jani@php.net Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php ------------------------------------------------------------------------ [2007-08-27 09:35:06] romain dot tartiere at healthgrid dot org Description: ------------ Considering a class that implements an interface and has methods that require many arguments. You may expect to make your life easier derivating this class and providing simpler methods. Reproduce code: --------------- <?php interface i_foo { function fooize($str, $n); } class c_foo implements i_foo { /* painful ($class->fooize($str, $n)) */ function fooize($str, $n) { echo "$str $n\n"; } } class c_bar extends c_foo { function fooize($str) { /* simple ($class->fooize($str)) */ $n = strlen($str); parent::fooize($str, $n); } } ?> Expected result: ---------------- This should not pose any kind of problem. Actual result: -------------- Fatal error: Declaration of c_bar::fooize() must be compatible with that of i_foo::fooize() ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=42439&edit=1
