PHP5中Session总结(一)
一. Session的配置与应用
1. bool session_start( void ); -- Initialize session data
2. $_SESSION[name] = value; -- Config session data
3. echo $_SESSION[name]; -- Use session
4. isset($_SESSION[name]); -- 判断session是否已配置
5. unset($_SESSION[name]); -- 删除session变量
6. bool session_destroy( void ); -- 删除所有session
* session_register,session_unregister, session_is_registered在PHP5中不再使用.
简单示例:
Php代码- <?php
- // Initialize the session.
- // If you are using session_name("something"), don't forget it now!
- session_start();
-
- // Unset all of the session variables.
- $_SESSION = array();
-
- // If it's desired to kill the session, also delete the session cookie.
- // Note: This will destroy the session, and not just the session data!
- if (isset($_COOKIE[session_name()])) {
- setcookie(session_name(), '', time()-42000, '/');
- }
-
- // Finally, destroy the session.
- session_destroy();
- ?>
