Paypal get access token with PHP cURL

Questions:

hello i’m using code used by other people who supposedly have gotten it to work and have gotten their token information retrieved. The code is as follows:

$ch = curl_init();
$clientId = "myclientid";
$secret = "mysecret";

curl_setopt($ch, CURLOPT_URL, "https://api.sandbox.paypal.com/v1/oauth2/token");
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSLVERSION , 6); //NEW ADDITION
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_USERPWD, $clientId.":".$secret);
curl_setopt($ch, CURLOPT_POSTFIELDS, "grant_type=client_credentials");

$result = curl_exec($ch);

if(empty($result))die("Error: No response.");
else
{
    $json = json_decode($result);
    print_r($json->access_token);
}

curl_close($ch); //THIS CODE IS NOW WORKING!

I retrieved this code from Paypal API with PHP and cURL and have seen it implemented in some others peoples code so i assume that it works. However i’m only receiving no response even though i am supplying the correct client id and secret (maybe a recent update has broken this code?).

The guide provided by Paypal on getting the access token is found here-> https://developer.paypal.com/docs/integration/direct/make-your-first-call/
however it demonstrates the solution in cURL and not through the PHP cURL extension so its alittle cryptic to me. Any help?

How to&Answers:

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.
