Inside the body of method foo() you can of course use syntax like
parent::foo(). But is there a way to call the parent version of
obj->foo() outside the class? That kind of syntax is allowed in C++, for
example: Aclass a; if (a.Aparent::foo()) ...;
Some contrived example to illustrate the point:
class AParent {
public function foo() { .. }
}
class A extends AParent {
public function foo() {
doit($this, __CLASS__, __FUNCTION__);
}
}
function doit($obj, $classname, $funcname) {
if (...)
// $obj->classname_parent::$funcname();
}
Thanks.
To use Richards example, but with a little different twist for accessing the parent methods/properties
class A
{
public __construct()
{
// ...
}
public function foo ()
{
// ...
}
}
class B extends A {
// Constructor
public function __construct ()
{
parent::__construct();
}
}
// And then...
$b = new B();
$b->foo();
This will bring all methods/properties from class A into class B.
You can choose to override class A methods/properties when you define class B.
But the idea here is that only need to write the methods/properties once in the parent class,
then you can extend your class with class A and have all the methods/properties available to you
within your current class.
It is good to practice the DRY principle here.
Note: Richard Heyes thanks for the code snippet
