How to push array into array using php class - php

Question

i would like to push some arrays into arrays and save it in a session.
And i tried to do this in a php class. I'm new to that so i made some mistakes and can't help me out.
my index.php:
<?php
session_start();
include("./cart.php");
//bezeichnung, preis, attribut
$myOrder = new Cart('17', 0.50, 'Book1');
$myOrder1 = new Cart('18', 1.50, 'Book2');
$_SESSION['products'] = array();
array_push($_SESSION['products'], $myOrder, $myOrder1);
echo '<pre>';
print_r($_SESSION['products']);
echo '</pre>';
my cart.php:
<?php
class Cart {
private $name;
private $price;
private $attr;
public function __construct($name, $price, $attr) {
$this->name = $name;
$this->price = $price;
$this->attr = $attr;
}
public function getName(){
return $this->name;
}
public function getPrice(){
return $this->price;
}
public function getAttr(){
return $this->attr;
}
}
i get something like this:
The part :Cart:private is really not good. This should be juest name,price and attr. I think i'm pushing the whole object into the array. How can i avoid this ?
Array
(
[0] => Cart Object
(
[name:Cart:private] => 17
[price:Cart:private] => 0.5
[attr:Cart:private] => Book1
)
[1] => Cart Object
(
[name:Cart:private] => 18
[price:Cart:private] => 1.5
[attr:Cart:private] => Book2
)
)

You can do a public method in your Cart class that will return all needed properties as an array.
class Cart {
private $name;
private $price;
private $attr;
public function __construct($name, $price, $attr) {
$this->name = $name;
$this->price = $price;
$this->attr = $attr;
}
public function getName(){
return $this->name;
}
public function getPrice(){
return $this->price;
}
public function getAttr(){
return $this->attr;
}
public function toArray(){
return array(
'name' => $this->getName(),
'price' => $this->getPrice(),
'attr' => $this->getAttr(),
);
}
}
Now in your index.php you can do:
array_push($_SESSION['products'], $myOrder->toArray(), $myOrder1->toArray());
