super();

You can use the parent keyword, if that's the same thing

class a
{
  function foo(){}
}
class b extends a
{
  function bar()
  {
    parent::foo();
  }
}

or simply:

class a
{
  function foo(){}
}
class b extends a
{
  function bar()
  {
    $this->foo();
  }
}

Not sure the parent will work here for parent designates the parent object in terms of instanciation.

Try it and see? 🙂

class a
{
  function foo()
  {
    echo "It works!!<br>";
  }
}
class b extends a
{
  function bar()
  {
    parent::foo();
  }
}
class c extends b
{
  function foo()
  {
    echo "Override it for fun!!<br>";
  }
  function bar()
  {
    echo $this->foo();
  }
}

$b = new b;
$b->bar();

$c = new c;
$c->bar();

I think, in Java terms, super() refers to the class one up in the heirarchy, which is what parent does in PHP.

Hmm odd behaviour in PHP 5 - if you omit the class constructor of a child class, the parent class constructor gets called.
