Thinkphp实现excel导出数据

前端：

点击导出触发click事件，传值export指令和args关键字(args是指我们是否有查询取哪些数据)到控制器

$(document).on("click", "#go-export", function () {
			var args = "";
			if($('#keyword').val() != ''){
				args = args + '/keyword/'+$('#keyword').val();
			}
			window.open('index/export/1'+args);
	    });

控制器：

        if(!empty($postData['keyword'])){
                $map['project_name'] = array('like','%'.$postData['keyword'].'%');
            }
	        $dataList = $goods->where($map)->select();
	        for ($i = 0; $i < sizeof($dataList); $i++) {
                    $result[$i]['id'] = $dataList[$i]['id'];
	            $result[$i]['合同号'] = $dataList[$i]['contract_number'];
	            $result[$i]['项目名称'] = $dataList[$i]['project_name'];
	            $result[$i]['销售月份'] = $dataList[$i]['sales_month'];
	            $result[$i]['房型'] = $dataList[$i]['room_type'];
                    $result[$i]['渠道'] = $dataList[$i]['channel'];
	            $result[$i]['售卖单价'] = $dataList[$i]['one_prices'];
	            $result[$i]['结算单价'] = $dataList[$i]['all_prices'];
	            $result[$i]['房间数量'] = $dataList[$i]['room_num'];
                    $result[$i]['减扣金额'] = $dataList[$i]['damount'];
	            $result[$i]['备注'] = $dataList[$i]['note'];
	            $result[$i]['更新日期'] = $dataList[$i]['update_time'];

                }
                $csv = "";
	        for($i=0;$i<sizeof($result);$i++){
	            if($i == 0){
	                $head = '"';
	                foreach($result[$i] as $key=>$value){
	                    if($head != '"'){
	                        $head .= '","';
	                    }
	                    $head .= $key;
	                }
	                $head .= ""
";
	                $csv .= $head;
	            }
	            $csv .= '"' . implode('","', $result[$i]) . '"' . "
";
	        }
	        $this->export($csv);
         }

下载控制器：ecport方法

 public function export($res){
	    header("Cache-Control: public");
	    header("Content-Description: File Transfer");
	    header("Content-Disposition: attachment; filename=".date('YmdHis').".csv");
	    header("Content-Type: application/csv");
	    header("Content-Transfer-Encoding: binary");
        print mb_convert_encoding($res,"GBK", "UTF-8");
        //print iconv('UTF-8', 'GBK//IGNORE', $res);
	
        }
