As curl need certificate verification requesting against to https endpoints. And to request to Bing Search API, we can just pass by the verification and which will still work fine.

Modify your function getJSON() as:

    if(!is_array($data)) throw new Exception("Query Data Not Valid. Type Array Required");
    //$data['$format'] = 'json';
    $url .= '?$format=json&' . http_build_query($data) ;
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
    curl_setopt($ch, CURLOPT_USERPWD,  "$this->apiKey:$this->apiKey");
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($ch, CURLOPT_TIMEOUT, 30);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
    $r = curl_exec($ch);
    $json = json_decode($r);

    if($json==null) throw new Exception("Bad Response: {$r}\n\n{$url}");
    return $json;

It works fine on my side.
