Message:

i am making a crypto converter as a project for my school. I am using a api key for that and the array of the api is:

array(10) {

      ["ADA"]=>

      float(1.024301)

      ["BNB"]=>

      float(402.82399)

      ["BTC"]=>

      float(40678.195596)

      ["DOGE"]=>

      float(0.140886)

      ["ETH"]=>

      float(2877.712908)

      ["LTC"]=>

      float(119.283982)

      ["NEO"]=>

      float(26.72906)

      ["USDT"]=>

      float(1.008932)

      ["XMR"]=>

      float(163.338038)

      ["XRP"]=>

      float(0.780664)

}

And this the loop i am using to loop through array in a select menu:

<form method="post" action="">

            <input type="text" name="amount" placeholder="Enter Amount"><br><br>

            <select name="from">

            <?php

            Foreach ($arr_usd["rates"] as $currency => $rates) {

                print "<option value='$rates'>$currency</option>";

            }

            ?>

            </select>

            <select name="to">

                <option value="USD">US Dollar</option>

                <option value="EUR">Euro</option>

            </select>

            <br><br>

            <button class="btn" name="convert_crypto">Convert</button>

            <div id="result"><?php include "post.php" ?>

            </div>

        </form>

The select menu works as it should be, it displays the crypto names. The calculation of the rates works too.

But when i echo the answer, it echoes the last key of the currency in this case XRP.

if(isset($_POST['convert_crypto'])) {

$amount = $_POST['amount'];

$from = $_POST['from'];

$to = $_POST['to'];

    if ($to == "USD") {

        $result = ($amount * round($from,2));

        echo $amount . " " . $currency . " = " . $result . " US Dollar";

    }    

}

My Answer:
BTC] => Bitcoin
[ETH] => Ethereum
[XRP] => Ripple
[LTC] => Litecoin
[BCH] => Bitcoin Cash
[ADA] => Cardano
[XLM] => Stellar
[NEO] => NEO
[EOS] => EOS
[XMR] => Monero
}

I am using a foreach loop to display these currencies in a select menu in my HTML form. However, when I run the code, it only shows the last key "XMR" in the select menu. Here is my code:

php

foreach($array as $key => $value) {
echo "$value";
}
?>



Can someone please help me figure out why only the last key is being displayed in the select menu and how I can fix this issue?
