[API]使用Yelp API / PHP

Question

First of all

• I want to use Yelp API with PHP.
• I want to get bearer access token, but can't.

Code

The code below is one that I executed.

$url = "https://api.yelp.com/oauth2/token";
$clientEncode = urlencode("?grant_type=client_credentials?client_id=MY_CLIENT_ID?client_secret=MY_CLIENT_SECRET");
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($curl, CURLOPT_POSTFIELDS, $clientEncode);
curl_setopt($curl, CURLOPT_HTTPHEADER, array("Content-Type: application/x-www-form-urlencoded"));
$response = curl_exec($curl);
$array = json_decode($response, true);
$arrayVal = array_values($array);
$bearer_token = $array->access_token;
echo '<pre>';
var_dump($array);
echo '</pre>';

And, the message below is the error message.

/home/ubuntu/workspace/index.php:21:
class stdClass#1 (1) {
public $error =>
class stdClass#2 (2) {
public $code =>
string(16) "VALIDATION_ERROR"
public $description =>
string(165) "client_id or client_secret parameters not found. Make sure to provide client_id and client_secret in the body with the application/x-www-form-urlencoded content-type"
}
}

Maybe, the use of cURL is Okay, I think, but I don't know how to add parameters on the url.

Please teach me more good practice.

Thanks.

    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curl, CURLOPT_POSTFIELDS, "grant_type=client_credentials");
    curl_setopt($curl, CURLOPT_HTTPHEADER, array("Content-Type: application/x-www-form-urlencoded"));
    $response = curl_exec($curl);
    $array = json_decode($response, true);
    $arrayVal = array_values($array);
    $bearer_token = $array->access_token;
