Folgende situation:

Code:

class A {
 function test() {
  return "test";
 }
class B extends A{
}
class C extends B{
 echo test();
}
}

Wirft mir "Call to undefined function test()".
Was mach ich falsch?

Code:

class A {

  public function __construct() {
  }
  
  public function test() {
    return 'A test';
  }
  
}

class B extends A {

  public function __construct() {
    parent::__construct();
  }

}

class C extends B {

  public function __construct() {
    parent::__construct();
  }

  public function test() {
    return parent::test();
  }

}

$o = new C();
echo $o->test();

oder...

Code:

class A {

  public function __construct() {
  }
  
  public function test() {
    return 'A test';
  }
  
}

class B extends A {

  public function __construct() {
    parent::__construct();
  }

}

class C extends B {

  public function __construct() {
    parent::__construct();
  }

}

$o = new C();
echo $o->test();
