ID: 52900 Updated by: [email protected] Reported by: e dot visciola at xaos dot it Summary: Protected instance method called by static method of the same class Status: Bogus Type: Bug Package: Class/Object related Operating System: WIN & OSX PHP Version: Irrelevant Block user comment: N New Comment: Java actually has more complicated semantics for protected: see http://java.sun.com/docs/books/jls/third_edition/html/names.html#6.6.2 : A protected member or constructor of an object may be accessed from outside the package in which it is declared only by code that is responsible for the implementation of that object. [Inside the same package, access is permitted] 6.6.2.1 Access to a protected Member Let C be the class in which a protected member m is declared. Access is permitted only within the body of a subclass S of C. In addition, if Id denotes an instance field or instance method, then: * If the access is by a qualified name Q.Id, where Q is an ExpressionName, then the access is permitted if and only if the type of the expression Q is S or a subclass of S. * If the access is by a field access expression E.Id, where E is a Primary expression, or by a method invocation expression E.Id(. . .), where E is a Primary expression, then the access is permitted if and only if the type of E is S or a subclass of S.

I try also in Java and the behaviour is the same. I'm sorry to have submit it. Good work ------------------------------------------------------------------------ [2010-09-21 17:09:13] [email protected] Not a bug. Inside the static method, the calling scope is A. The scope of instanceMethod is also A. Protected methods are accessible whenever their scope and the calling scope are in the same class hierarchy. ------------------------------------------------------------------------ [2010-09-21 16:02:01] e dot visciola at xaos dot it Description: ------------ When I call a protected instance method of an object inside a class method of "the same type" I'd like to have an error. The example explain: Test script: --------------- class A { protected function instanceMethod() { echo 'Instance method called, but it is not right because instance method is protected<br />'; } public static function staticMethod() { echo 'Static method called<br />'; $a = new A(); $a->instanceMethod(); } } A::staticMethod(); Expected result: ---------------- That was generated an error to access the protected method Actual result: -------------- Static method called Instance method called, but it is not right because instance method is protected ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=52900&edit=1
