如何按 coinmarketcap api v1 按美元价格对响应进行排序？

Question

I am using coinmarketcap api to get top 100 cyptocurrencies. By default, the response is sorted by rank, but i want the response to be sorted by price .

I want to display them sorted by price in descending order.

$data = json_decode(file_get_contents('https://api.coinmarketcap.com/v1/ticker/'), true);

foreach ($data as $key => $value) {
    $id = $value["id"];
    $name = $value["name"];
    $price_usd = $value["price_usd"];
    $percent_change_24h = $value['percent_change_24h'];
    $percent_change_7d = $value['percent_change_7d'];

    echo "<tr>";
    echo "<td>". $id . "<span>" . $name . "/ USD</span></td>";
    echo "<td>". $price_usd ."</td>";
    echo "<td><i class = 'fa fa-caret-up' aria-hidden = 'true'>". $percent_change_24h . "<span> " . $percent_change_7d . "</span></i></td>";
    echo    "</tr>";  
 }

How about array-multisort ? you can do it like:

$data = json_decode(file_get_contents('https://api.coinmarketcap.com/v1/ticker/'), true);
array_multisort(array_column($data, "price_usd"), SORT_DESC, $data);

Or you can change price_usd to any field you need and nop $data will be sorted form highest to lowest and you can run your for-loop on it
