Defining an array within a class in php

Question

I have the following array in php

   $criteria = array();
     $criteria['x'] = array();
     $criteria['y'] = array();
     $criteria['z'] = array();

I also have a class defined in php with property xyz

   $screenerItem = new \StdClass();
   $screenerItem->xyz =0;

How can i make my array $criteria as a part of my screenerItem class property?

I tried this but didnt work,can someone help me out to know what is wrong with this syntax:

   $screenerItem->$criteria = array();
   $screenerItem->$criteria['x'] = array();
   $screenerItem->$criteria['y'] = array();
   $screenerItem->$criteria['z'] = array();

Answer 1

As @Nahid suggested you can fill your class poperty in constructor. Another way (if your class property is public) is:

$criteria_array = array(/* your array here */);
$screenerItem->criteria = $criteria_array;
// Notice that I don't use $ in front of criteria as it's class property.

And of course your attemp is legal too:

// Once again no $ before criteria
$screenerItem->criteria = array();
$screenerItem->criteria['x'] = array();

Answer 2

Try this

class MyClass{
    public $criteria=array();

    function __construct(){
        $this->criteria=array(
            'x'=>array(),
            'y'=>array(),
            'z'=>array()
            );
    }
}


$screenItem=new MyClass;

or You may use this convenction

class MyClass{
    public $criteria=array();

    function __construct($array){
        $this->criteria=$array;
    }
}


$data=array(
    'x'=>array(),
    'y'=>array(),
    'z'=>array()
);

$screenItem=new MyClass($data);
