What is a difference between a method and a function?

Question

What is the difference between a method and a function? Is it that a method returns a value and a function doesn\'t?

Answer 1

Method is actually a function used in the context of a class/object.

When you create a function outside of a class/object, you can call it a function but when you create a function inside a class, you can call it a method.

class foo {
   public function bar() { // a method
     ........
   }
}

---

function bar() {  // a function not part of an object
}

---

So an object can have methods (functions) and properties (variables).
