Thinkphp5匯出Excel功能

1. 網上下載PHPExcel包，http://www.php.cn/xiazai/leiku/1491 下載後只需要Classes目錄下的檔案即可
2. 放在Thinkphp/vendor/下面，前端直接跳轉到該控制器
3. 前臺直接跳到該控制器方法下

<?php

namespace app\admin\controller;

use think\Controller;
use think\Request;
use think\Db;
class Excel extends Controller
{
   public function
 
 index()
   {
       $time = time();
       $xlsData = Db::table('oa_attendance')->where("morning", "=", "1")->where("afternoon", "=", "1")
           ->alias('a')
           ->join('oa_user u', 'a.uid = u.uid')
           ->join('oa_com c', 'u.factory = c.cid')
           ->select
 
();
        //這裡引入PHPExcel檔案注意路徑修改
       vendor("PHPExcel");                                     
       vendor("PHPExcel.Writer.Excel5");
       vendor("PHPExcel.Writer.Excel2007");
       vendor("PHPExcel.IOFactory");
       $objExcel = new \PHPExcel();                   
       $objWriter = \PHPExcel_IOFactory:
 
:createWriter($objExcel, 'Excel2007');
       $objActSheet = $objExcel->getActiveSheet();
       $key = ord("A");
       $letter =explode(',',"A,B,C,D,E,F,G");
       $arrHeader = array('ID','姓名','工作單位','電話','職位','上班打卡時間','下班打卡時間');
       $lenth =  count($arrHeader);
       for($i = 0;$i < $lenth;$i++) {
           $objActSheet->setCellValue("$letter[$i]1","$arrHeader[$i]");
       };
       foreach($xlsData as $k=>$v){
           $k +=2;
           $objActSheet->setCellValue('A'.$k, $v['id']);
           $objActSheet->setCellValue('B'.$k, $v['name']);
           $objActSheet->setCellValue('C'.$k, $v['com_name']);
           $objActSheet->setCellValue('D'.$k, $v['phone']);
           $objActSheet->setCellValue('E'.$k, $v['job']);
           $objActSheet->setCellValue('F'.$k, date("m-d H:i",$v['morningtime']));
           $objActSheet->setCellValue('G'.$k, date("m-d H:i",$v['afternoontime']));
           $objActSheet->getRowDimension($k)->setRowHeight(20);
       }
       $width = array(20,20,15,10,10,30,10,15);
       //設定表格的寬度
       $objActSheet->getColumnDimension('A')->setWidth($width[3]);
       $objActSheet->getColumnDimension('B')->setWidth($width[1]);
       $objActSheet->getColumnDimension('C')->setWidth($width[0]);
       $objActSheet->getColumnDimension('D')->setWidth($width[5]);
       $objActSheet->getColumnDimension('E')->setWidth($width[5]);
       $objActSheet->getColumnDimension('F')->setWidth($width[5]);
       $objActSheet->getColumnDimension('G')->setWidth($width[5]);

       $outfile = "員工考勤表.xls";
       ob_end_clean();
       header("Content-Type: application/force-download");
       header("Content-Type: application/octet-stream");
       header("Content-Type: application/download");
       header('Content-Disposition:inline;filename="'.$outfile.'"');
       header("Content-Transfer-Encoding: binary");
       header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
       header("Pragma: no-cache");
       $objWriter->save('php://output');    //這裡直接匯出檔案

   }

}

4. 這裡是目錄結構
   這是下載出來的，只需要Classes檔案下的
