PHP practice project notes COOKIES

Mainly set cookies when logging in and out. To save login and safe exit

1: Set on the login page

//Set the value of cookies
_setcookies($_rows['tg_username'], $_rows['tg_uniqid'],$_clean['time']);
_location(null,'index.php');

Step 2: Generate cookie,

/**
 * _setcookies
 * @param unknown $_username
 * @param unknown $_uniqid
 */function _setcookies($_username,$_uniqid,$_time){
    setcookie('username',$_username);
    setcookie('uniqid',$_uniqid);
    switch ($_time) {
        case '0' : // 设置浏览器进程setcookie ( 'username', $_username );
            setcookie ( 'uniqid', $_uniqid );
            break;
        case '1' : // 一天的进程setcookie ( 'username', $_username, $_time () + 86400 );
            setcookie ( 'uniqid', $_uniqid, $_time () + 86400 );
            break;
        case '2' : // 一周的进程setcookie ( 'username', $_username, $_time () + 604800 );
            setcookie ( 'uniqid', $_uniqid, $_time () + 604800 );
            break;
        case '0' : // 一个月的进程setcookie ( 'username', $_username, $_time () + 2592000 );
            setcookie ( 'uniqid', $_uniqid, $_time () + 2592000 );
            break;
    }
}

Step 3: Set

//登录的情况,就是防止登陆后通过在浏览器中直接连接再次登录function _login_state(){
    if (!isset($_COOKIE['username'])) {
        _alert_back("登录状态无法就行本操作！");
    }
}

//删除cookiesfunction _unsetcookies(){
    setcookie('username','',time()-1);
    setcookie('uniqid','',time()-1);
    _session_destroy();//删除session    _location(null,'index.php'); //做跳转}

in login status Step 4 on login page and logout Page plus

//登录状态    _login_state();
