Get parent extends class in php?

Your code suggested you used parent which in fact is what you need. The issue lies with the magic CLASS variable.

I have the oop php code: class a { // with propertie and functions } class be extends a { public function test() { echo __CLASS__; // this is be // parent::__CLASS__ // error } } $b = new b(); $b->test(); I have a few parent class (normal and abstract) and many child classes. The child classes extend the parent classes. So when I instantiate the child at some point I need to find out what parent I called.

For example the funciton b::test() will return a How can I get (from my code) the class a from my class b? Thanks php class parent extend link|improve this question edited Nov 26 '11 at 14:38Hunter McMillen4,2001311 asked Nov 26 '11 at 14:35ana50912 83% accept rate.

Your code suggested you used parent, which in fact is what you need. The issue lies with the magic __CLASS__ variable. The documentation states: As of PHP 5 this constant returns the class name as it was declared.

Which is what we need, but as noted in this comment on php. Net: claude noted that __CLASS__ always contains the class that it is called in, if you would rather have the class that called the method use get_class($this) instead. However this only works with instances, not when called statically.

If you only are in need of the parent class, theres a function for that aswell. That one is called get_parent_class.

You can use get_parent_class: class A {} class B extends A { public function test() { echo get_parent_class(); } } $b = new B; $b->test(); // A This will also work if B::test is static. NOTE: There is a small difference between using get_parent_class without arguments versus passing $this as an argument. If we extend the above example with: class C extends B {} $c = new C; $c->test(); // A We get A as the parent class (the parent class of B, where the method is called).

If you always want the closest parent for the object you're testing you should use get_parent_class($this) instead.

Class a { // with propertie and functions } class be extends a { public function test() { echo get_parent_class($this); } } $b = new b(); $b->test().

You can use reflection to do that: Instead of parent::__CLASS__; use $ref = new ReflectionClass($this); echo $ref->getParentClass()->getName().

Use class_parents instead. It'll give an array of parents. '); } } $c = new C; $c->test(); // B -> A.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
