Get a value from curl result

Question

I am trying to get the ID from the result. How I can print only ID?

I have tried decode $resp but seems like the issue with array.

    //API Url
    $url = 'https://api.clover.com:443/v3/merchants/'.$merchantid.'/orders/';

    //Initiate cURL.
    $ch = curl_init($url);

    //The JSON data.
    $jsonData = array(
        'state' => 'open',
        'title' => '0010-W'
    );

    $headers = array(
        'Content-type: application/json',
        'Authorization: Bearer '.$authtoken.' ',
    );
    //Encode the array into JSON.
    $jsonDataEncoded = json_encode($jsonData);

    //Tell cURL that we want to send a POST request.
    curl_setopt($ch, CURLOPT_POST, 1);

    //Attach our encoded JSON string to the POST fields.
    curl_setopt($ch, CURLOPT_POSTFIELDS, $jsonDataEncoded);

    //Set the content type to application/json
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); //<=====This was missing.

    curl_setopt($ch, CURLOPT_HEADER, false);

    $resp = curl_exec($ch);


    $data = json_decode($resp, true);
    echo 'ID: '.$data['id'];

{
"href": "https://www.clover.com/v3/merchants/***/orders/D4MHB7M5D0P86", 
"id": "D4MHB7M5D0P86", 
"currency": "USD", 
"title": "0010-W", 
"taxRemoved": false, 
"isVat": false, 
"state": "open", 
"manualTransaction": false, 
"groupLineItems": true, 
"testMode": false, 
"createdTime": 1553976014000, 
"clientCreatedTime": 1553976014000, 
"modifiedTime": 1553976014000
}

I expect to get the ID, but I get empty result.

The question that mentioned as duplicate is explaining different thing not cURL data.

Resolved - The question edited with the answer. CURLOPT_RETURNTRANSFER Needs to be set in order to print the data. Tested and work perfectly.

Try changing `$data = json_decode($resp);` to `$data = json_decode($resp, true);`. — Xxmarijnw, Mar 30 '19 at 20:42
Change `$resp['id'];` to `$data['id'];` ...you decoded the data but thens didn't use it, and tried to access the un-decoded version instead. — ADyson, Mar 30 '19 at 21:34
If `$resp` does indeed contain the data shown, then your code works - here's a demo: http://sandbox.onlinephpfunctions.com/code/f45d812245eec02e04fdd23846f9da76b5ceb226 . So I can only assume that either a) the cURL call is failing, or b) the data in $resp is not the data you've shown us, or c) somehow you are not looking in the right place for the output? — ADyson, Mar 30 '19 at 22:10

@miken32 the extracting data part is fine, assuming the data being supplied is what is stated in the question...see my last comment for proof. I don't think that's the issue, so the duplicate doesn't answer it. If OP is getting no output then the problem is elsewhere, as I've described — ADyson, Mar 30 '19 at 22:46
@ADyson you was right with `$data` is not including the correct data. After adding `CURLOPT_RETURNTRANSFER` $data now showing needed data. — Profile, Mar 31 '19 at 02:35
