PHP Exercise Program Notes Cookies

The main point is to set up cookies when logging in and exiting. To save logins and secure exits

1: Setup on login page

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

Step two: Generate Cookies,

/** * _setcookies * @param unknown $_username * @param unknown $_uniqid*/function_setcookies ($_username,$_uniqid,$_time){    Setcookie(' username ',$_username); Setcookie(' Uniqid ',$_uniqid); Switch($_time) {         Case' 0 '://Set Browser ProcessSetcookie(' username ',$_username ); Setcookie(' Uniqid ',$_uniqid );  Break;  Case' 1 '://the process of the daySetcookie(' username ',$_username,$_time() + 86400 ); Setcookie(' Uniqid ',$_uniqid,$_time() + 86400 );  Break;  Case' 2 '://a week of progressSetcookie(' username ',$_username,$_time() + 604800 ); Setcookie(' Uniqid ',$_uniqid,$_time() + 604800 );  Break;  Case' 0 '://one-month processSetcookie(' username ',$_username,$_time() + 2592000 ); Setcookie(' Uniqid ',$_uniqid,$_time() + 2592000 );  Break; }}

Step three: Set up in the login state

// login situation is to prevent login after login by direct connection in the browser function _login_state () {    if (!  Isset($_cookie[' username '])) {        _alert_back ("login status cannot be done on this operation! ");    }}

// Delete Cookies function _unsetcookies () {    setcookie(' username ', ', Time()-1);     Setcookie (' Uniqid ', ', Time()-1);    _session_destroy (); // Delete Session    _location (null// do jump }

The fourth step in the login page and exit page Plus

// Login Status    _login_state ();

The above describes the PHP exercise project notes of the cookies, including the content, I hope the PHP tutorial interested in a friend helpful.
