Pull specific value from JSON with PHP

I'm trying to pull the price from the following JSON but can't seem to figure out how to reference the actual values:

{"cards": [ { "high": "0.73", "volume": 1, "percent_change": "-2.67", "name": "Lightning Bolt", "url": "http://blacklotusproject.com/cards/Revised+Edition/Lightning+Bolt/", "price": "0.73", "set_code": "3ED", "average": "0.73", "change": "-0.02", "low": "0.73"}], "currency": "USD" }

So far I've got this code, which gets into the cards array but I'm unsure how to get farther - every attempt I've tried returns null.

$json = file_get_contents($url); $data = json_decode($json, TRUE);
echo var_dump($data[cards]);

Can someone shed light on what I need to do?

To access using a string literal array index, always use quotes.

$data["cards"]

$data['cards'] is an array itself, so you could do:

foreach ($data['cards'] AS $carditem) {
    echo $carditem['high'];
    ...
}

to get all items in that array, or if you only want the first item $data['cards'][0]['...']

$data['cards'] has another array within it. You will need to access this array with index 0. For instance, $data['cards'][0]['high'] and so on.
