php curl_exec returns empty

Question

 $ch = curl_init();
 curl_setopt($ch, CURLOPT_URL, $url);
 curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
 curl_setopt($ch, CURLOPT_PROXY, $proxy); // $proxy is ip of          


        

Answer 1

You're trying to access a HTTP response code before you actually make the HTTP call. Reverse the execution as follows:

$response = curl_exec($ch);
$httpCode = curl_getinfo($ch , CURLINFO_HTTP_CODE); // this results 0 every time
