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excelpublic 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')->setCellValue('H2', '商品单价')->setCellValue('I2', '实付金额')->setCellValue('J2', '商品佣金')->setCellValue('K2', '会员佣金')->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]['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_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,$name,'Xlsx');}//下载private function downloadExcel($newExcel,$filename,$format){ob_end_clean();ob_start();// $format只能为 Xlsx 或 Xlsif ($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/1.0exit;}
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_upyongjin'])->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
