session_unset()
You should know that on recent PHP only the first one of these functions works correctly. And if you use the other two, var_dump will print you the result you expected (session cleaned up), but the session file on the server won't be cleaned up. So use the first one.
代码如下 | 复制代码 |
function session_clean1($logout=false) foreach($v as $x) function session_clean2($logout=false) function session_clean3($logout=false) ?> |
On previous php (<<5.1.4) releases at least the third one worked correctly.
释放当前在内存中已经创建的所有$_SESSION变量,但不删除session文件以及不释放对应的session id
session_destroy()
删除当前用户对应的session文件以及释放session id,内存中的$_SESSION变量内容依然保留
因此,释放用户的session所有资源,需要顺序执行如下代码:
PHP代码
代码如下 | 复制代码 |
// Initialize the session. // Unset all of the session variables. // If it's desired to kill the session, also delete the session cookie. // Finally, destroy the session. |
