Session保存到数据库的php类,需要的朋友可以参考下。
代码如下:
class SessionToDB
{
private $_path = null;
private $_name = null;
private $_pdo = null;
private $_ip = null;
private $_maxLifeTime = 0;
public function __construct(PDO $pdo)
{
session_set_save_handler(
array(&$this, 'open'),
array(&$this, 'close'),
array(&$this, 'read'),
array(&$this, 'write'),
array(&$this, 'destroy'),
array(&$this, 'gc')
);
$this->_pdo = $pdo;
$this->_ip = !empty($_SERVER['REMOTE_ADDR']) ? $_SERVER['REMOTE_ADDR'] : null;
$this->_maxLifeTime = ini_get('session.gc_maxlifetime');
}
public function open($path,$name)
{
return true;
}
public function close()
{
return true;
}
public function read($id)
{
$sql = 'SELECT * FROM session where PHPSESSID = ?';
$stmt = $this->_pdo->prepare($sql);
$stmt->execute(array($id));
if (!$result = $stmt->fetch(PDO::FETCH_ASSOC)) {
return null;
} elseif ($this->_ip != $result['client_ip']) {
return null;
} elseif ($result['update_time']+$this->_maxLifeTime
