Paypal get access token with PHP cURL

Well it seems that it is now a requirement to declare what type of SSL Version to use, thus the code above will work when curl_setopt($ch, CURLOPT_SSLVERSION , 6); //tlsv1.2 is inserted.

Just tested the API and I can confirm this code is working :

(No SSL options)

    $curl = curl_init();
    curl_setopt_array($curl, array(
    CURLOPT_URL => "https://api.sandbox.paypal.com/v1/oauth2/token",
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_ENCODING => "",
    CURLOPT_MAXREDIRS => 10,
    CURLOPT_TIMEOUT => 30,
    CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
    CURLOPT_CUSTOMREQUEST => "POST",
    CURLOPT_USERPWD => $PAYPAL_CLIENT_ID.":".$PAYPAL_SECRET,
    CURLOPT_POSTFIELDS => "grant_type=client_credentials",
    CURLOPT_HTTPHEADER => array(
    "Accept: application/json",
    "Accept-Language: en_US"
    ),
    ));

    $result= curl_exec($curl);

    $array=json_decode($result, true); 
    $token=$array['access_token'];

    echo "<pre>";
    print_r($array);
