這篇文章主要為大家詳細(xì)介紹了PHP實(shí)現(xiàn)生成Excel文件并導(dǎo)出的方法，文中的示例代碼講解詳細(xì)，對(duì)我們學(xué)習(xí)PHP有一定的幫助，需要的可以參考一下

在現(xiàn)在的項(xiàng)目里，不管是電商項(xiàng)目還是別的項(xiàng)目，在管理端都會(huì)有導(dǎo)出的功能，比方說訂單表導(dǎo)出，用戶表導(dǎo)出，業(yè)績(jī)表導(dǎo)出。這些都需要提前生成excel表，然后在導(dǎo)出，實(shí)際上是在代碼里生成一張excel表，然后通過下載api進(jìn)行導(dǎo)出的。好了先給大家講一下示例

利用php導(dǎo)出excel我們大多會(huì)直接生成.xls文件，這種方便快捷。

首先我們先在項(xiàng)目中引入幾個(gè)類

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

然后我們?cè)谶M(jìn)行封裝一個(gè)生成并導(dǎo)出excel表的方法，這里我們用訂單表做示例

//訂單信息導(dǎo)出excel
    public function order_outputProjectExcel($info){
        $newExcel = new Spreadsheet();//創(chuàng)建一個(gè)新的excel文檔
        $objSheet = $newExcel->getActiveSheet();//獲取當(dāng)前操作sheet的對(duì)象
        $date = date('Ymd',time());
        $name = '訂單信息表';
        $objSheet->setTitle($name);//設(shè)置當(dāng)前sheet的標(biāo)題
 
        //樣式設(shè)置 - 合并和拆分
        $objSheet->mergeCells('A1:P1'); //合并單元格
        //$sheet -> unmergeCells('C3:G3'); //拆分單元格
        $objSheet->setCellValue('A1',$name);
 
        //設(shè)置第一欄的中文標(biāo)題
        $objSheet->setCellValue('A2', '編號(hào)')
            ->setCellValue('B2', '商品圖片')
            ->setCellValue('C2', '商品名稱')
            ->setCellValue('D2', '會(huì)員編號(hào)')
            ->setCellValue('E2', '直屬')
            ->setCellValue('F2', '非直屬')
            ->setCellValue('G2', '訂單號(hào)')
            ->setCellValue('H2', '商品單價(jià)')
            ->setCellValue('I2', '實(shí)付金額')
            ->setCellValue('J2', '商品傭金')
            ->setCellValue('K2', '會(huì)員傭金')
            ->setCellValue('L2', '直屬傭金')
            ->setCellValue('M2', '非直屬傭金')
            ->setCellValue('N2', '支付時(shí)間')
            ->setCellValue('O2', '支付渠道')
            ->setCellValue('P2', '訂單狀態(tài)');
 
        //寫入數(shù)據(jù)
        $dataCount = count($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']);
            }
        }
 
        //設(shè)定樣式
        //所有sheet的表頭樣式 加粗
        $font = [
            'font' => [
                'bold' => true,
                'size' => 14,
            ],
        ];
        $objSheet->getStyle('A1:P1')->applyFromArray($font);
 
        //樣式設(shè)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的內(nèi)容樣式-加黑色邊框
        $borders = [
            'borders' => [
                'outline' => [
                    'borderStyle' => Border::BORDER_THIN,
                    'color' => ['argb' => '000000'],
                ],
                'inside' => [
                    'borderStyle' => Border::BORDER_THIN,
                ]
            ],
        ];
        $objSheet->getStyle('A1:P'.$k)->applyFromArray($borders);
 
        //設(shè)置寬度
        $cell = ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P'];
        foreach($cell as $k=>$v){
            $objSheet->getColumnDimension($v)->setWidth(20);
 
//            $objSheet->getColumnDimension($v)->setAutoSize(true);
        }
 
        $this->downloadExcel($newExcel,$name,'Xlsx');
    }
    
    
    
    
    //下載
    private function downloadExcel($newExcel,$filename,$format)
    {
        ob_end_clean();
        ob_start();
        // $format只能為 Xlsx 或 Xls
        if ($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');

        //通過php保存在本地的時(shí)候需要用到
        // $objWriter->save($dir.'/demo.xlsx');
 
        //以下為需要用到IE時(shí)候設(shè)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;
    }

到這一步其實(shí)就已經(jīng)成功了95%了。剩下的5%只需要你調(diào)用上面的方法傳入正確的參數(shù)即可

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

這里的$info是你的訂單詳情。必須要做時(shí)間篩選，如果不做時(shí)間篩選的話數(shù)據(jù)量一多，你的系統(tǒng)會(huì)崩的。

這里的for循環(huán)就是你傳入的 $info。如果說你的 $info 是空的那么導(dǎo)出的excel打開的時(shí)候還會(huì)出現(xiàn)

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']);
  }

最后就是這樣的效果
