TRY USING MY FUNCTION

function curl_grab_page($site,$proxy,$proxystatus){
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
    if ($proxystatus == 'on') {
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE); // change your ssl if true
        curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, TRUE);
        curl_setopt($ch, CURLOPT_PROXY, $proxy);
    }
    curl_setopt($ch, CURLOPT_COOKIEFILE, "cookie.txt"); // if you are using a cookie
    curl_setopt($ch, CURLOPT_URL, $site);
    ob_start();      // prevent any output
    return curl_exec ($ch); // execute the curl command
    ob_end_clean();  // stop preventing output
    curl_close ($ch);
}

PHP:

USE LIKE THIS

curl_grab_page("http://www.google.com","","off");

PHP:

this works

 

Strange function. Lines after return will never be executed. So you have ob_start without end, and non-closed curl handle.
