Can't connect with API to my freshdesk Account with PHP

Hi,

I'm using a PHP code to try to fetsh my tickets. Sample of code used :

$api_key = "xxxxxxxxxxxxxxx";

$password = "x";

$yourdomain = "yyyyyyyyyy";

// Return the tickets that are new or opend & assigned to you

// If you want to fetch all tickets remove the filter query param

$url = "https://$yourdomain.freshdesk.com/api/v2/tickets";

$ch = curl_init($url);

curl_setopt($ch, CURLOPT_HEADER, true);

curl_setopt($ch, CURLOPT_USERPWD, "$api_key:$password");

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$server_output = curl_exec($ch);

$info = curl_getinfo($ch);

//var_dump($info);exit;

$header_size = curl_getinfo($ch, CURLINFO_HEADER_SIZE);

$headers = substr($server_output, 0, $header_size);

$response = substr($server_output, $header_size);

 when i var_dump $info i can see that my code add HTTP and try to connect to HTTP://https://domain.freshdesk....

How can i resolve this problem ? thanks.
