$ch = curl_init();

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, false);

curl_setopt($ch, CURLOPT_URL, 'https://app.reviewapi.io/api/v0/reviews?' . http_build_query($dataQuery));

curl_setopt($ch, CURLOPT_HTTPHEADER, array(
	"Content-Type: application/json",
	"apikey: $apiKey",
));

$responseData = curl_exec($ch);
curl_close($ch);

?>
