ThinkPHP(百万级)数据分表技术的例子

class MemberModel extends AdvModel {
protected $partition = array('field'=>'username','type'=>'id','num'=>'4');
    public function getDao($data=array()) {
        $data = empty($data) ? $_POST : $data;
        $table = $this->getPartitionTableName($data);
        return $this->table($table);
    }
}

class MemberAction extends BaseAction {
    public function login() {
        if($this->isPost()) {
            $this->validToken();
            $dao = D('Member')->getDao();
            $res = $dao->where('username = '.$_POST['username'])->find();
            // output 为自定义方法
            // $isAjax - bool
            $this->output(false);
        }
        $this->display();
    }
}
