thinkPHP excel 導出

1. 下載PHPExcel，放到指定路徑下；
2. 查詢數據庫數據，導出；

    /*全部導出數據方法*/
    public function allExp()
    {
        $bgdate = htmlspecialchars($_POST['bgdate']);
        $enddate = htmlspecialchars($_POST['enddate']);
        $map = 'create_time > '.strtotime($bgdate).' and create_time <'.(strtotime($enddate) + 86400);

        //鏈接所導出的數據表
        $xlsModel = D('Bi');
        //“bilibili,mobile,create_time”爲所查詢的字段，“”查詢條件
        $mobile_list  = $xlsModel->field('mobile,create_time')->where($map)->select();

        $count=1;//導出Excel序號排列

        $data = array();
        //循環查詢後的數據，進行每一列
        foreach ($mobile_list as $k=>$mobile_info){
            $data[$k][ID] = $count++;//序號列
            $data[$k][mobile] = $mobile_info['mobile'];//名稱列
            $data[$k][create_time] = date("Y-m-d H:i:s",$mobile_info['create_time']);//地址列
        }

        //每列表的名稱
        foreach ($data as $field=>$v){
            if($field == 'ID'){
                $headArr[]='序號';
            }

            if($field == 'mobile'){
                $headArr[]='電話';
            }

            if($field == 'create_time'){
                $headArr[]='創建時間';
            }
        }

        $filename="bi活動電話信息數據表";//所導出的保存文件名稱
        $sss=$this->getExcel($filename,$headArr,$data);//調用導出引用方法


    }
