PHP实现生成Excel文件并导出的示例详解_开发_开发者

在现在的项目里，不管是电商项目还是别的项目，在管理端都会有导出的功能，比方说订单表导出，用户表导出，业绩表导出。这些都需要提前生成excel表，然后在导出，实际上是在代码里生成一张excel表，然后通过下载api进行导出的。好了先给大家讲一下示例

利用php导出excel我们大多会直接生成.xls文件，这种方便快捷。

首先我们先在项目中引入几个类

use \PhpOffice\PhpSpreadsheet\Spreadsheet;
use \PhpOffice\PhpSpreadsheet\IOFactory;
use \PhpOffice\PhpSpreadsheet\Cell\Coordinate;
use PhpOffice\PhpSpreadsheet\Style\Border;
use PhpOffice\PhpSpreadsheet\Style\Alignment;

然后我们在进行封装一个生成并导出excel表的方法，这里我们用订单表做示例

//订单信息导出excel
    public function order_outputProjectExcel($info){
        $newExcel = new Spreadsheet();//创建一个新的excel文档
        $objsheet = $newExcel->getActiveSheet();//获取当前操作sheet的对象
        $date = date('Ymd',time());
        $name = '订单信息表';
        $objSheet->setTitle($name);//设置当前sheet的标题
 
        //样式设置 - 合并和拆分
        $objSheet->mergeCells('A1:P1'); //合并单元格
        //$sheet -> unmergeCells('C3:G3'); //拆分单元格
        $objSheet->setCellValue('A1',$name);
 
        //设置第一栏的中文标题
        $objSheet->setCellValue('A2', '编号')
            ->setCellValue('B2', '商品图片')
            ->setCellValue('C2', '商品名称')
            ->setCellValue('D2', '会员编号')
            ->setCellValue('E2', '直属')
            ->setCellValue('F2', '非直属')
            ->setCellValue('G2', '订单号')
          编程  ->setCellValue('H2', '商品单价')
            ->setCellValue('I2', '实付金额')
            ->setCellValue('J2', '商品佣金')
            ->setCellValue('K2', '会员佣金')
            编程->setCellValue('L2', '直属佣金')
            ->setCellValue('M2', '非直属佣金')
            ->setCellValue('N2', '支付时间')
            ->setCellValue('O2', '支付渠道')
            ->setCellValue('P2', '订单状态');
 
        //写入数据
        $dataCount = count($info);
        $k = 2;
        
        if($dataCount == 0){
            exit;
        }else{
            for ($i=0;$i<$dataCount;$i++){
                $k = $k + 1;
                $order=$i+1;
                $objSheet->setCellValue('A' . $k, $info[$i]['id'])
                    ->setCellValue('B' . $k, $info[$i]['jsgoods_image'])
                    ->setCellValue('C' . $k, $info[$i]['goods_name'])
                    ->setCellValue('D' . $k, $info[$i]['user_num'])
                    ->setCellValue('E' . $k, $info[$i]['user_upteam'])
                    ->setCellValue('F' . $k, $info[$i]['user_un_upteam'])
                    ->setCellValue('G' . $k, $info[$i]['order_id'])
                    ->setCellValue('H' . $k, $info[$i]['goods_price'])
                    ->setCellValue('I' . $k, $info[$i]['payment'])
                    ->setCellValue('J' . $k, $info[$i]['goods_yongjin'])
                    ->setCellValue('K' . $k, $info[$i]['user_yongjin'])
                    ->setCellValue('L' . $k, $info[$i]['user_up_yongjin'])
                    ->setCellValue('M' . $k, $info[$i]['user_un_upyongjin'])
                    ->setCellValue('N' . $k, $info[$i]['paymenttime'])
                    ->setCellValue('O' . $k, $info[$i]['pay_way_ch'])
                    ->setCellValue('P' . $k, $info[$i]['status_ch']);
            }
        }
 
        //设定样式
        //所有sheet的表头样式 加粗
        $font = [
            'font' => [
                'bold' => true,
                'size' => 14,
            ],
        ];
        $objSheet->getStyle('A1:P1')->applyFromArray($font);
 
        //样式设置 - 水平、垂直居中
        $styleArray = [
            'alignment' => [
                'horizontal' => Alignment::HORIZONTAL_CENTER,
                'vertical' => Alignment::VERTICAL_CENTER
            ],
        ];
        $objSheet->getStyle('A1:P2')->applyFromArray($styleArray);
 
        //所有sheet的内容样式-加黑色边框
        $borders = [
            'borders' => [
                'outline' => [
                    'borderStyle' => Border::BORDER_THIN,
                    'color' => ['argb' => '000000'],
                ],
                'inside' => [
                    'borderStyle' => Border::BORDER_THIN,
                ]
            ],
        ];
        $objSheet->getStyle('A1:P'.$k)->applyFromArray($borders);
 
        //设置宽度
        $cell = ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P'];
        foreach($cell as $k=>$v){
            $objSheet->getColumnDimension($v)->setWidth(20);
 
//            $objSheet->getColumnDimension($v)->setAutoSize(true);
        }
 
        $this->downloadExcel($newExcel,$name,'Xlsx');
    }
    
    
    
    
    //下载
    private function downloadExjavascriptcel($newExcel,$filename,$format)
    {
        ob_end_clean();
        ob_start();
        // $format只能为 Xlsx 或 Xls
        if ($format == 'Xlsx') {
            header('Content-Type: application/vnd.openXMLformats-officedocument.spreadsheetml.sheet');
        } elseif ($format == 'Xls') {
            header('Content-Type: application/vnd.ms-excel');
        }
//  strtolower($format)
        header("Content-Disposition: attachment;filename="
            . $filename . '.' . strtolower($format));
        header('Cache-Control: max-age=0');
        $objWriter = IOFactory::createWriter($newExcel, $format);
        $objWriter->save('php://output');

        //通过php保存在本地的时候需要用到
        // $objWriter->save($dir.'/demo.xlsx');
 
        //以下为需要用到IE时候设置
        // If you're serving to IE 9, then the following may be needed
        //header('Cache-Control: max-age=1');
        // If you're serving to IE over SSL, then the following may be needed
        //header('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); // Date in the past
        //header('Last-Modified: ' . gmdate('D, d M Y H:i:s') . ' GMT'); // always modified
        //header('Cache-Control: cache, must-revalidate'); // HTTP/1.1
        //header('Pragma: public'); // HTTP/1.0
        exit;
    }

到这一步其实就已经成功了95%了。剩下的5%只需要你调用上面的方法传入正确的参数即可

model('Apimodel')->order_outputProjectExcel($info);

这里的$info是你的订单详情。必须要做时间筛选，如果不做时间筛选的话数据量一多，你的系统会崩的。

这里的for循环就是你传入的 $info。如果说你的 $info 是空的那么导出的excel打开的时候还会出现

for ($i=0;$i<$dataCount;$i++){
    $k = $k + 1;
    $order=$i+1;
    $objSheet->setCellValue('A' . $k, $info[$i]['id'])
        ->setCellValue('B' . $k, $info[$i]['goods_image'])
        ->setCellValue('C' . $k, $info[$i]['goods_name'])
        ->setCellValue('D' . $k, $info[$i]['user_num'])
        ->setCellValue('E' . $k, $info[$i]['user_upteam'])
        ->setCellValue('F' . $k, $info[$i]['user_un_upteam'])
        ->setCellValue('G' . $k, $info[$i]['order_id'])
        ->setCellValue('H' . $k, $info[$i]['goods_price'])
        ->setCellValue('I' . $k, $info[$i]['payment'])
        ->setCellValue('J' . $k, $info[$i]['goods_yongjin'])
        ->setCellValue('K' . $k, $info[$i]['user_yongjin'])
        ->setCellValue('L' . $k, $info[$i]['user_up_yongjin'])
        ->setCellValue('M' . $k, $info[$i]['user_un_uphppyongjin'])
        ->setCellValue('N' . $k, $info[$i]['paymenttime'])
        ->setCellValue('O' . $k, $info[$i]['pay_way_ch'])
        ->setCellValue('P' . $k, $info[$i]['status_ch']);
  }

最后就是这样的效果
