Question

So there are two things that I am stuck on now. First

class DisplayTaxonomy {
public $MyArray[]= new DisplayTaxonomy();  //the compiler says syntax error
//things I have tried 
//public $ss[]= new Object();  


}

Second! in a function like this:

public function whatever()
{
     $Temp = new DisplayTaxonomy();
     $Temp->setADTitle("1");
     $MyArray[]= $Temp;//works just fine.
     //then i tried to return the array 
      return $MyArray[];


}

I get the following
//Cannot use [] for reading in C:\xampp\htdocs\wordpress\wp-//content\themes\twentyeleven\page.php on line 52
then in the client side

$y=new DisplayTaxonomy();
$myArray[]=new DisplayTaxonomy();//works fine dont know why I cant do this in theclass.
$myArray[]=$y->getArrayOfDisplayTaxonomyObjects();
echo $myArray[0]->getADTitle();

Answer 1

It seems you want to create a class that handles a collection of Taxonomy objects. In that case you should have two classes, instead of making a class store instances of itself.

class TaxonomyContainer 
{
    private $collection = array();

    public function addElement(DisplayTaxonomy $element)
    {
        $this->collection[] = $element;
    }

    public function getElements()
    {
        return $this->collection;
    }
}

class DisplayTaxonomy
{
    private $adTitle;

    public function setAdTitle($adTitle)
    {
        $this->adTitle = $adTitle;
    }

    //and other functionality the Taxonomy object should have
}

Then you can avoid the ugly self replicating behaviour and separate your concerns.

$container = new TaxonomyContainer();
$element = new DisplayTaxonomy();
$container->addElement($element);

On the next level, it might be worth considering the use of one of PHP’s predefined interfaces for the Container class.
