You can set CURLOPT_STDERR and CURLOPT_VERBOSE curl options to save your errors in a file. Also, you may use curl_error() function. BTW, by default, curl should show all errors in STDERR.

Besides, for general check, you can simply specify selected proxy in you browser configuration properties, try to open specific service in browser and see, whether correct response is returned.

UPDATE:

CURLOPT_HTTPPROXYTUNNEL is used to make curl call CONNECT HTTP method when requesting proxy server (see here for details). I tested code without this option - it worked successfully.

Code I used:

$proxy = "75.147.173.215:8080";
$proxy = explode(':', $proxy);
$url = "http://google.com";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_PROXY, $proxy[0]);
curl_setopt($ch, CURLOPT_PROXYPORT, $proxy[1]);
curl_setopt($ch, CURLOPT_HEADER, 1);

$exec = curl_exec($ch);

echo curl_error($ch);
print_r(curl_getinfo($ch));
echo $exec;
