How to display price from json in php?

Question

PHP

Good afternoon. There is this code:

<?php if(in_category(4)) :
$tick = file_get_contents('https://api.coinmarketcap.com/v1/ticker/bitcoin?convert=RUB');
$data = json_decode($tick, TRUE);

$price = $data[0]["price_rub"];
echo "<div>Текущая цена: ".$price." РУБ</div>";
?>
<?php endif; ?>

It safely displays the cost in the rubric. But soon this api version will stop working, and there will be the following one:
https://api.coinmarketcap.com/v2/ticker/1/?convert=RUB
Not enough knowledge, how to correct the code so that the cost is displayed? Thanks in advance!

Answer 1

$price = $data["data"]["quotes"]["RUB"]["price"];
echo "<div>Текущая цена: ".$price." РУБ</div>";
