"Friend" access for certain classes or interfaces

Posted by tcs-1986 2 months ago

PHP doesn't have a feature about "friend" access for certain classes or interfaces. Certain classes should access private or protected methods in another "friendly" classes. ```php class ABC { friend A; private $testPrivate = "private OK"; protected $testProtected = "protected OK"; public $testPublic = "public OK"; } class A { static function friend_test() { $foo = new ABC(); echo $foo->$testPrivate; echo $foo->$testProtected; echo $foo->$testPublic; } } class B { static function friend_test() { $foo = new ABC(); echo $foo->$testPrivate; echo $foo->$testProtected; echo $foo->$testPublic; } } class C extends A { // ... } A:friend_test(); // private OK // protected OK // public OK B:friend_test(); // error: $test is a private method // error: $test is a protected method // public OK C:friend_test(); // private OK // protected OK // public OK ```
