Echo JSON数组特定元素

I'm confused about how I can echo a certain element in my JSON array.

Under time series (1min), I would like to output 1. open. In order to give me the actual value for it.

So far, i'm only able to output the complete array.

Link to JSON file is: https://www.alphavantage.co/query?function=TIME_SERIES_INTRADAY&symbol=MSFT&interval=1min&apikey=demo

Also, i'm using wordpress.

Here is the code i'm using:

$request = wp_remote_get('https://www.alphavantage.co/query?function=TIME_SERIES_INTRADAY&symbol=MSFT&interval=1min&apikey=demo');

if( is_wp_error( $request ) ) {
    return false; // Bail early
}

$body = wp_remote_retrieve_body( $request );

$data = json_decode($body, true);

echo $body;

</div>

    You got the array, you simply need to loop over it.

    //...
    $data = json_decode($body, true);
    
    foreach ($data['Time Series (1min)'] as $date => $row) {
        echo $date.' => '.$row['1. open'].'<br>';
    }
    

    Its a little tricky if you want just one value as its not the greatest structure, the date being the key. But you can use array_values() function to fix that.

    $min = array_values($data['Time Series (1min)']);
    
    echo $min[0]['1. open']; //84.2000
