Loop thru 3dimensional array

Question

Its the first time I am working with a 3-dimensional array, maybe its just a syntax erorr which I can't find, but I guess its something else - so I am asking you. This is my PHP array which I want to loop thru. At the moment it has only one element at its highest index for testing purposes:

<?
$packages = array(
    "package1" => array (
        "EUW" => array (
            "id" => 1,
            "imgsrc" => "images/packages/background01.jpg",
            "title" => "blabla",
            "desc" => "blabla",
            "level" => 15,
            "rp" => 16975,
            "ip" => 40000,
            "price" => 35,
            "soldout" => true
        ),
        "EUNE" => array (   
            "id" => 1,
            "imgsrc" => "images/packages/background01.jpg",
            "title" => "blabla",
            "desc" => "blabla",
            "level" => 15,
            "rp" => 16975,
            "ip" => 40000,
            "price" => 35,
            "soldout" => true
        ),
        "NA" => array ( 
            "id" => 1,
            "imgsrc" => "images/packages/background01.jpg",
            "title" => "blabla",
            "desc" => "blabla",
            "level" => 15,
            "rp" => 16975,
            "ip" => 40000,
            "price" => 35,
            "soldout" => true
        ),
        "BR" => array ( 
            "id" => 1,
            "imgsrc" => "images/packages/background01.jpg",
            "title" => "blabla",
            "desc" => "blabla",
            "level" => 15,
            "rp" => 16975,
            "ip" => 40000,
            "price" => 35,
            "soldout" => true
        ),
        "LAN" => array (    
            "id" => 1,
            "imgsrc" => "images/packages/background01.jpg",
            "title" => "blabla",
            "desc" => "blabla",
            "level" => 15,
            "rp" => 16975,
            "ip" => 40000,
            "price" => 35,
            "soldout" => true
        )
    )
);
?>

How I try to check the amount of my packages (which should be one?):

require_once("inc/packages.php");
if(isset($packages)) echo "ok";
else echo "not ok";

This outputs me: "Not ok".

Answer 1

I would probably use a foreach :

foreach($packages as $package) {
   var_dump($package);
}
