Status: Not a bug Type: Bug Package: Scripting Engine problem Operating System: OpenSuSE 11.0 PHP Version: 5.2.8 Block user comment: N Private report: N New Comment: it's not resolve at 2018-1-2 in PHP7.0.12-NTS Previous Comments: ------------------------------------------------------------------------ [2016-08-26 02:29:04] luoziluojun at 126 dot com it's not resolve at 2016/8/26 ------------------------------------------------------------------------ [2015-01-21 16:01:59] t dot kmieliauskas at gmail dot com Hey, 2008 called, they said they wanted their errors back!

Still valid in 5.5.12... ------------------------------------------------------------------------ [2012-02-11 19:10:18] ldr at ldrutledge dot com I understand the discussion above. The warning is because some possible method calls may fail due to incomplete knowledge at compile-time. However this causes the warning: class A { public function foo(StdClass $a) {;}} class B extends A { public function foo($a) {;}} as does this: class A { public function foo($a) {;}} class B extends A { public function foo(StdClass $a) {;}} In the case of function bar(A $a, A $b){$a->foo($b);} The second form can fail at run-time, but the first can not and should not trigger the error. ------------------------------------------------------------------------ [2012-02-09 06:10:45] eyal dot t at zend dot com was wondering why the order of the class declarations affects whether a notice is given, that is while abstract class B extends A { public static function foo($str){ echo $str; } } abstract class A { public static function foo(){ echo 'bar'; } } causes the strict standard notice to show, the reversed order does not: abstract class A { public static function foo(){ echo 'bar'; } } abstract class B extends A { public static function foo($str){ echo $str; } } ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
