Hi,

I'm trying to run the code bellow but with no success. No error message but the value is not changed.

class A {
  public $item_limit;

   public function __construct(){
        $this->item_limit = null;
   }

  function test() {
    echo $this->item_limit;
  }

}

class B extends A {

   function My_test() {
        $tools = new A();
        if (isset($limit))
             $tools->item_limit = $limit;
   }
}  

Any help will be appreciated plz.

Best Regards

It's a little hard, from you code, to see what you are trying to do...

Where does the $limit variable come from? In your code above it will hold no value, and the line

if (isset($limit))

will never be true.

Also, I'm not sure why you would create a new instance of class A inside the method My_test() in class B. Since B extends A, B is kind of a instance of class A already and you probably won't need to create a new instance of it.

My guess is, that you're trying to do something like this, which should work just fine.

PHP Code:

class A {
   private $item_limit;

   public function __construct() {
      $this->item_limit= null;
   }

   public function printLimit() {
      echo $this->item_limit;
   }
}

class B extends A {
   public function setLimit($limit) {
      $this->item_limit = $limit;
   }
}

$b = new B();
$b->setLimit(12);
$b->printLimit(); // should print 12 


Hi lizciz,

Thank you very much for your reply. In fact I tried your code but with no succes then I created the new complex one written here.

Anyway, the issue was that the $item_limit value was nulled again in another place I fixed it, thank you.

Best Regards
