Previous Comments: ------------------------------------------------------------------------ [2015-07-17 12:30:36] mbrodala at pagemachine dot de I stumbled upon a similar error while trying to use a trait to make static method calls mockable in tests: http://3v4l.org/s5t3s The issue can be avoided here by not using the "StaticCall" trait in subclasses of "ChildClass" but in reality classes should just use the traits they need and not rely on the trait usage of a parent class. Is there an error on my side? ------------------------------------------------------------------------ [2011-09-05 07:32:09] tyrael@php.net for the record: the segfault is caused by an infinite recursion (B->func), and that happens, because the $this in the B->func() points to C, which causes parent::func to point to itself. btw. I find it really unintentional that call_user_func can be used with both passing an object instance and a static call reference as a method name. we also have failing tests for this particular bug: Zend/tests/bug48770.phpt Zend/tests/bug48770_2.phpt Zend/tests/bug48770_3.phpt imo as we have this behavior for some time now, I think we should keep it, and update the tests.

The solution is: call_user_func_array('parent::func', $args); instead of call_user_func_array(array($this, 'parent::func'), $args); ------------------------------------------------------------------------ [2009-09-25 08:08:07] dmitry dot revenko at businessmedia dot ru I also used this pattern in some critical moments, and it proved to be very useful. Yes, I know about PHP 3's "call_user_func() now propagates $this even if the callee is the parent class". But I don't know - why? Why so simple working logic was ruined in new version? Isn't it straght that call_user_func_array(array( $this, 'parent::func' ), $args) should call first found parent method func? ------------------------------------------------------------------------ [2009-08-01 01:51:07] jani@php.net Also note: This works fine with PHP_5_2 :) ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
