Question

 curl_setopt($ch, CURLOPT_URL, $url);
 curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

 curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
 curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
 curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
 curl_setopt($ch, CURLOPT_TIMEOUT, 10);
 $httpCode = curl_getinfo($ch , CURLINFO_HTTP_CODE); // this results 0 every time

curl_exec will return false when the request failed. Adjust your function to this :

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_PROXY, $proxy); // $proxy is ip of proxy server
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);

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

if ($response === false) 
    $response = curl_error($ch);

echo stripslashes($response);

curl_close($ch);

This way u'll see the curl error

You can also add curl_errno($ch) to get the error number (or 0 if no error occurred).

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

Try:

curl_setopt($ch, CURLOPT_TIMEOUT, 50);

Maybe the response is longer than 10.

I had the same issue, I solved like this.

The result return 0 mean that you can not connect to the server so please recheck your proxy and increase the timeout :)
