I've written a php function and some helper functions that checks for cookies when somebody lands on a page but it's not so fast. I want to know is there any way to make it faster or improve it i know it's possible to check for cookies client side using javascript but what if it is disabled also so i need a pure server side solution.<?phpfunction check_cookie(){    if(is_cookie_disabled()){        header(location:cookie_is_disabled.php);        exit;    }        }function is_cookie_disabled(){    $curr_url = $_SERVER['PHP_SELF'];    if(isset($_COOKIE['testCookie']) && !(isset($_COOKIE['cookie']))){        $original_url = original_url ($curr_url);        header(location: .$original_url);        setcookie(cookie, 'enabled');        exit;    } elseif(!(isset($_COOKIE['testCookie']))) {        if(isset($_GET['temp'])){                            return true;        } else{            if(if_parameters_exist_in_url($curr_url)){                $url = $curr_url.&temp=temp;            } else {                $url = $curr_url.?temp=temp;            }            header(location: .$url);            setcookie(testCookie, 'test');            exit;                      }    }    return false;}function original_url ($curr_url){    if (!empty($_GET)){        if (isset($_GET['temp'])) {            if(count($_GET)>0){                return removeqsvar($curr_url, 'temp');            } else {                return removeallvars($curr_url);            }        }    }    return $curr_url;}    function removeqsvar($url, $varname) {    return preg_replace('/([?&])'.$varname.'=[^&]+(&|$)/','$1',$url);}function removeallvars($url){    return $url = strtok($url, '?');}function if_parameters_exist_in_url($url){    if (strpos($url, '=')) {        return true;    } else {        return false;    }}    //at the top of your pagescheck_cookie();?>
