thinkphp 奇怪的问题

  session 的问题

public function read($sessID) {
 

        $hander = is_array($this->hander)?$this->hander[1]:$this->hander; 

        //echo "SELECT session_data AS data FROM ".$this->sessionTable." WHERE session_id = '$sessID'   AND session_expire >".time(); 

        $res = mysql_query("SELECT session_data  FROM ".$this->sessionTable." WHERE session_id = '$sessID'   AND session_expire >".time(),$hander); 

        if($res) { 


            print_r(mysql_fetch_array($res)); 

            $row = mysql_fetch_array($res); 

            print_r($row); 

            return $row['session_data']; 

        }else{ 

            echo 'ddddd'; 

        } 

        return ""; 

   }

输出

Array ( [0] => [session_data] => ) Array ( [0] => verify|s:32:"908ada5a7e8c361cc1ecb07ec84802e0"; [session_data] => verify|s:32:"908ada5a7e8c361cc1ecb07ec84802e0"; )



908ada5a7e8c361cc1ecb07ec84802e0Array ( [verify] => 908ada5a7e8c361cc1ecb07ec84802e0 )

print_r(mysql_fetch_array($res));去掉

Array ( [0] => [session_data] => )
