here we are getting response without echo on the top of the page but we don't need to that type of out put so we have disabled using span tag.
echo ""; //to hide the curl response
$ch = curl_init();
$header = array('api_key:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx','Content-Type: application/json');
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $method);
if($postdata!=""){
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata);
}
$response = curl_exec($ch);
$info = curl_getinfo($ch);
$responseBody = json_decode($response);
print_r($responseBody);
echo $response; // display 1(one)
curl_close($ch);
echo "";
and result is : 1
