Question

How do I call child function from parent static function ?

In php5.3 there is a built in method called get_called_class() to call child method from parent class. But my server is running with php 5.1.

Is there any way can do this ?

I want to call it from a static function . So that I can not use “$this”

So i should use “self” keyword.

Below example my parent class is “Test123” , from the parent class static function “myfunc” am trying to call child class function like this “self::test();”

abstract class Test123
{

  function __construct()
  {
    // some code here
  }

  public static function myfunc()
  {
    self::test();
  }

  abstract function test();
}

class Test123456 extends Test123
{
  function __construct()
  {
    parent::__construct();
  }

  function test()
  {
    echo "So you managed to call me !!";
  }

}

$fish = new Test123456();
$fish->test();
$fish->myfunc();

Edit: What you try to achieve is not possible with PHP 5.1. There is no late static bindings ^{PHP Manual} in PHP 5.1, you need to explicitly name the child class to call the child function: Test123456::test(), self will be Test123 in a static function of the class Test123 (always) and the static keyword is not available to call a static function in PHP 5.1.

If you are referring to a static parent function, then you need to explicitly name the parent (or child) for the function call in php 5.1:

parentClass::func();
Test123456::test();

In PHP 5.3 you can do this instead with the static keyword ^{PHP Manual} to resolve the called class’ name:

static::func();
static::test();

If those are non-static, just use $this ^{PHP Manual}:

$this->parentFunc();
$this->childFunc();

Or if it has the same name, use parent ^{PHP Manual}:

parent::parentFunc();

(which is not exactly what you asked for, just putting it here for completeness).

Get_called_class() has been introduced for very specific cases like to late static bindings ^{PHP Manual}.
