Curl install in cent os but not working

Hello,

I have install CURL in cent OS.

I can see in my PHPINFO.

I also install LARAVEL.

But when i call curl return 0.

i have also setup firewall and allowed 80 and 443 port

 $html_brand = "www.google.com";
                $ch = curl_init();

                $options = array(
                    CURLOPT_URL            => $html_brand,
                    CURLOPT_RETURNTRANSFER => true,
                    CURLOPT_HEADER         => true,
                    CURLOPT_FOLLOWLOCATION => true,
                    CURLOPT_ENCODING       => "",
                    CURLOPT_AUTOREFERER    => true,
                    CURLOPT_CONNECTTIMEOUT => 120,
                    CURLOPT_TIMEOUT        => 120,
                    CURLOPT_MAXREDIRS      => 10,
                );
                curl_setopt_array( $ch, $options );
                $response = curl_exec($ch); 
                $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);

                if ( $httpCode != 200 ){
                    echo "Return code is {$httpCode} \n"
                        .curl_error($ch);
                } else {
                    echo "<pre>".htmlspecialchars($response)."</pre>";
                }

It’s “Return code is 0”;

how i resolved this issue.

I am sure issue from server.

any comments guys ?
