php multiple classes and methods with same name

Question

If I call "myClass::getItems()" from the "workingCLass" which getId method will be called? The one that echos "hello" or "bye"? Thank you.

class myClass extends otherClass { function getId(){ echo "hello"; } } class otherClass{ function getItems(){ $this->getId(); } function getId(){ echo "bye"; } } class workingClass extends myClass { function __construct(){ $this->getItems(); } }

The one with "hello", because you explicitly specified which one to call.

The problem, though, is that it's not static and you call it in a static context.

EDIT: With $this, it will not call anything, because there's no getItems() in the workingClass. If workingClass extended the otherClass it would do the "bye" thingie.

Your right, it should say $this->getItems(). If I did not have the "getId" method in "myClass", would it echo "bye"?

This will result in fatal error, since you are calling this method statically (::) and inside this method you are using $this special variable, that refers to workingClass(object from which it was called) and workingClass has no getId method.

OK, now after fixing the example I can say that it will output 'hello', because when calling method from the object ($this->) PHP will always run one defined in latest child class.
