PHP实现生成Excel文件并导出的示例详解

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")    ->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
