#43231 [Asn->Bgs]: array-based callback syntax is overly E_STRICT

ID: 43231 Updated by: helly@php.net Reported By: chuck at horde dot org -Status: Assigned +Status: Bogus Bug Type: Scripting Engine problem -Operating System: MacOS 10.4 +Operating System: * -PHP Version: 5.3CVS-2007-11-10 (CVS) +PHP Version: 5.2.* -Assigned To: colder +Assigned To: helly New Comment: 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 This is indeed the correct behavior. You do not pass in a valid callback. If you call hello() directly you get an E_STRICT. Now call_user_func[_array]() tries to bind this function and cannot because it is not a valid one. It used to work in 5.2 for BC sakes, because I overlooked this in 5.0. When I first noticed this issue in 5.1, we couldn't change it in 5.1 and we also decided to not change this in 5.2.

So methods that are not explicitly declared static can't be used this way even with E_STRICT off. Putting static in front of the function makes it work, but of course results in a parse error when the code is run under PHP 4. Reproduce code: --------------- <?php class Test { function hello() { echo "hello\n"; } } call_user_func(array('Test', 'hello')); Expected result: ---------------- hello Actual result: -------------- Warning: call_user_func() expects parameter 1 to be valid callback, array given in /Users/chuck/callback.php on line 11 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=43231&edit=1
