PHP5中Session小结(一)
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 // 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(); ?>
