php 设置cookie与清除cookie方法

function makecookie($var, $value, $life = 0, $prefix = 0) //设置cookie
{
 global $cookiepre, $cookiedomain, $cookiepath, $timestamp, $_server;
 setcookie(($prefix ? $cookiepre : '').$var, $value,
 $life ? $timestamp + $life : 0, $cookiepath,
 $cookiedomain, $_server['server_port'] == 443 ? 1 : 0);
}

function clearcookies() //清除cookie
{
 global $uid, $username, $pw, $adminid;
 makecookie('auth', '', -86400 * 365);
 $uid = $adminid = 0;
 $username = $pw = '';
}

makecookie('111','www.111cn.net');
//清除cookie
clearcookies();

//下面兴一个支持二级域名cookie函数吧。

function setcookielive($name, $value='', $expire=0, $path='', $domain='', $secure=false, $httponly=false) {
    //set a cookie as usual, but also add it to $_cookie so the current page load has access
    $_cookie[$name] = $value;
    return setcookie($name,$value,$expire,$path,$domain,$secure,$httponly);
}

setcookielive('webab','111cn',time()+86000,'/','111cn.net');

//一入门级cookie设置方法

setcookie("cookie[three]", "cookiethree");
setcookie("cookie[two]", "cookietwo");
setcookie("cookie[one]", "cookieone");

// after the page reloads, print them out
if (isset($_cookie['cookie'])) {
    foreach ($_cookie['cookie'] as $name => $value) {
        echo "$name : $value
";
    }
}
