php实现将Session写入数据库

这篇文章主要介绍了php实现将Session写入数据库的相关资料,需要的朋友可以参考下

使用session_set_save_handler()函数，将Session的内容写入数据库

prepare($sql); $stmt->execute(array($PHPSESSID)); if(!$result = $stmt->fetch(PDO::FETCH_ASSOC)){ return ''; } if(self::$ip == $result['client_ip']){ self::destroy($PHPSESSID); return ''; } if(($result['update_time']+self::$lifetime)<: self::destroy return public static function write phpsessid from session where self::>prepare($sql); $stmt->execute(array($PHPSESSID)); if($result=$stmt->fetch(PDO::FETCH_ASSOC)){ if($result['data'] != $data || self::$time > ($result['update_time']+30)){ $sql = "update session set update_time=?,data=? where PHPSESSID = ?"; $stmt = self::$handler->prepare($sql); $stmt->execute(array($self::$time,$data,$PHPSESSID)); } }else{ if(!empty($data)){ try{ $sql = "insert into session(PHPSESSID,update_time,client_ip,data) values(?,?,?,?)"; }catch(PDOException $e){ echo $e->getMessage(); } $sth = self::$handler->prepare($sql); $sth->execute(array($PHPSESSID,self::$time,self::$ip,$data)); } } return true; } public static function destroy($PHPSESSID){ $sql = "delete from session where PHPSESSID = ?"; $stmt = self::$handler->prepare($sql); $stmt->execute(array($PHPSESSID)); return true; } public static function gc($lifetime){ $sql = "delete from session where update_timeprepare($sql); $stmt->execute(array(self::$time-$lifetime)); return true; } } //使用PDO连接数据库 try{ $pdo = new PDO("mysql:host=localhost;dbname=session","root","hwj193"); }catch(PDOException $e){ echo $e->getMessage(); } //传递数据库资源 Session::start($pdo);
