在HTML中格式化来自JSON对象的PHP数组

Question

How can I format the following output (Using cURL in PHP to parse a json object to an array and display properly formatted text in HTML)

function curlTwitch() {

  $ch = curl_init();

  curl_setopt($ch, CURLOPT_URL, "https://api.twitch.tv/kraken/streams/?game=Overwatch");
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET");

  curl_setopt($ch, CURLOPT_HTTPHEADER, array (
    'Accept: application/vnd.twitchtv.v5+json',
    'Client-ID: x8j9dhw66qkgbsw67bfwtos4hyfeww'
  ));


$result = curl_exec($ch);

var_dump( json_decode($result, true) );

//echo json_encode($result, JSON_PRETTY_PRINT);

}

My current output fills the page in an unreadable format and is shown as something like:

array(2) { ["_total"]=> int(872) ["streams"]=> array(25) { [0]=> array(14) { 
["_id"]=> int(30799425120) ["game"]=> string(9) "Overwatch" 
["broadcast_platform"]=> string(4) "live" ["community_id"]=> string(0) "" 
["community_ids"]=> array(0) { } ["viewers"]=> int(6104) ["video_height"]=> 
int(900) ["average_fps"]=> int(60) ["delay"]=> int(0) ["created_at"]

If you're outputting to HTML, try adding a <pre> tag before the output:

<pre><?= json_encode($result, JSON_PRETTY_PRINT); ?></pre>

This should produce the following output:

{
    "_total": 872,
    "streams": [
        {
            "_id": 30799425120,
            "game": "Overwatch",
            "broadcast_platform": "live",
            "community_id": '',
            "community_ids": [],
            "viewers": 6104,
            "video_height": 900,
            "average_fps": 60,
            "delay": 0,
            "created_at": '...'
        }
    ]
}

Hope that helps.
