Hello everyone. I'm a self learner that is very new to programming. I'm trying to print out the value of ["mid"]  from a json_decode variable in the code shown below: 

I'm trying to use for each to access the value of "mid'. using foreach function. I know I'm not doing it the right way. please help me or show me an easy was to go around it.

/////the json resopnd form the url is  :

{"terms":"http://www.xe.com/legal/dfs.php","privacy":"http://www.xe.com/privacy.php","from":"USD","amount":1.195,"timestamp":"2021-02-09T16:52:00Z","to":[{"quotecurrency":"NGN","mid":454.6559871014}]}
/////////////////////////////////////////////////

<?php
$auth = base64_encode("username:password");
$context = stream_context_create([
    "http" => [
        "header" => "Authorization: Basic $auth"
    ]
]);
$homepage = file_get_contents("https://xecdapi.xe.com/v1/convert_from?to=NGN&amount=1.195", false, $context );
$json = json_decode($homepage, TRUE);
foreach ($json as $price){
    echo $price['mid'];
};

?>

If you

echo '<pre>$json = ', print_r($json, 1), '</pre>';

you get

$json = Array
(
    [terms] => http://www.xe.com/legal/dfs.php
    [privacy] => http://www.xe.com/privacy.php
    [from] => USD
    [amount] => 1.195
    [timestamp] => 2021-02-09T16:52:00Z
    [to] => Array
        (
            [0] => Array
                (
                    [quotecurrency] => NGN
                    [mid] => 454.6559871014
                )

        )

)

Then follow the array keys to the value you want

So you need

echo $json['to'][0]['mid'];        // --> 454.6559871014

[edit] Alternatively

foreach ($json['to'] as $price)  {
    printf('%s %0.2f<br>', $price['quotecurrency'], $price['mid'] );        // --> NGN 454.66
}
