How to decode curl output? - php

Question

Please help me to decode this below output, which I got when I run cURL.
Here is my code:
$headers = array(
'Accept:application/json',
'X-TB-PARTNER-AUTH: 45504852:abcdksalkrjwejkrjr'
);
$process = curl_init();
curl_setopt($process, CURLOPT_URL,"https://api.opentok.com/session/create");
curl_setopt($process, CURLOPT_HTTPHEADER, $headers);
curl_setopt($process, CURLOPT_HEADER, 1);
curl_setopt($process, CURLOPT_POST, 1);
curl_setopt($process, CURLOPT_POSTFIELDS, 'p2p.preference=disabled');
curl_setopt($process, CURLOPT_RETURNTRANSFER, 1);
$server_output = curl_exec($process);
print_r($server_output);
And my output is:
HTTP/1.1 200 OK
Server: nginx
Date: Mon, 14 Mar 2016 10:10:19 GMT
Content-Type: application/json
Connection: keep-alive
Access-Control-Allow-Origin: *
Content-Length: 180
Strict-Transport-Security: max-age=31536000; includeSubdomains
[{"session_id":"2_MX40NTUwNDg1Mn5-MTQ1Nzk1MDIxOTVNGZmUwS1N3bFF2LzhvREZORVN-fg","partner_id":"404852","create_dt":"Mon Mar 12 03:10:19 PDT 2016","media_server_url":""}]

Answer 1

Are you confused by the fact HTTP headers are included in the output?
If so - drop this line: curl_setopt($process, CURLOPT_HEADER, 1);
That is responsible for including the HTTP headers in the output. (See http://php.net/manual/en/function.curl-setopt.php )

Answer 2

Use json_decode function to parse it as an object or array:
$result = '[{"session_id":"2_MX40NTUwNDg1Mn5-MTQ1Nzk1MDIxOTVNGZmUwS1N3bFF2LzhvREZORVN-fg","partner_id":"404852","create_dt":"Mon Mar 12 03:10:19 PDT 2016","media_server_url":""}]';
echo "<pre>";
$json = json_decode($result,true);
print_r($json);// You may access print_r($json{0}->create_dt); etc
