Why is php curl host not resolving?

Question

PHP

Host not resolved from Php script. From the console everything finds and everything works. What can be wrong?

$url = 'http://google.com/';

        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_VERBOSE, true);
        var_dump(curl_exec($ch));
        var_dump(curl_error($ch));

Result

bool(false) string(34) "Could not resolve host: google.com"
