代码仓库：https://github.com/PHPOffice/PhpSpreadsheet

1、进入/dayrui目录

2、使用命令行安装类

也可以使用迅睿的第三方类仓库：https://gitee.com/dayrui/composer，将下载的文件放到dayrui/Vendor/目录中。

3、需要将vendor目录命名为Vendor（首字母大写）

4、新建控制器文件：

dayrui/App/Demo/Controllers/Excel.php

<?php namespace Phpcmf\Controllers;

class Excel extends \Phpcmf\Common
{

// excel文件导出 方法一，使用 setCellValueByColumnAndRow
   public function index() {

$data = [
            ['title1' => '111', 'title2' => '222'],
            ['title1' => '111', 'title2' => '222'],
            ['title1' => '111', 'title2' => '222']
        ];
        $title = ['第一行标题', '第二行标题'];

// Create new Spreadsheet object
        $spreadsheet = new \PhpOffice\PhpSpreadsheet\Spreadsheet();
        $sheet = $spreadsheet->getActiveSheet();
        
        
        $sheet->getColumnDimension('A')->setWidth(50);// 给A列设置宽度
        $sheet->getColumnDimension('B')->setAutoSize(true); // 给B列设置自动宽度
        
        
        $sheet->getRowDimension('1')->setRowHeight(30);// 给第一行设置行高，一般第一行是字段名称
        
        // 设置第一行背景和居中等
        $abc = array('A', 'B', 'C', 'D', 'E', 'F', 'G'); // 有多少列就列多少字母
        foreach ($abc as $a) {
            $sheet->getStyle($a.'1')->getFill()->setFillType(\PhpOffice\PhpSpreadsheet\Style\Fill::FILL_SOLID)->getStartColor()->setRGB("efefef");
            $sheet->getStyle($a.'1')->getFont()->setBold(true);
            $sheet->getStyle($a.'1')->getFont()->setSize(14);
             // 第一行居中
            //$sheet->getStyle($a.'1')->getAlignment()->setHorizontal(\PhpOffice\PhpSpreadsheet\Style\Alignment::HORIZONTAL_CENTER);
            // 第一行居中对齐
            $sheet->getStyle($a.'1')->getAlignment()->setVertical(\PhpOffice\PhpSpreadsheet\Style\Alignment::VERTICAL_CENTER);
        }
        
            
        $sheet->setTitle('导出结果');// 工作表格名称

// 方法一，使用 setCellValueByColumnAndRow
        //表头
        //设置单元格内容
        foreach ($title as $key => $value) {
            // 单元格内容写入
            $sheet->setCellValueByColumnAndRow($key + 1, 1, $value);
        }
        $row = 2; // 从第二行开始
        foreach ($data as $item) {
            $column = 1;
            foreach ($item as $value) {
                // 单元格内容写入
                $sheet->setCellValueByColumnAndRow($column, $row, $value);
                $column++;
            }
            $row++;
        }

// Redirect output to a client’s web browser (Xlsx)
        header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
        header('Content-Disposition: attachment;filename="01simple.xlsx"');
        header('Cache-Control: max-age=0');
        // 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

$writer = \PhpOffice\PhpSpreadsheet\IOFactory::createWriter($spreadsheet, 'Xlsx');
        $writer->save('php://output');
        exit;

}
   
   // 导出 方法二，使用 setCellValue
   public function index2() {

// Create new Spreadsheet object
        $spreadsheet = new \PhpOffice\PhpSpreadsheet\Spreadsheet();
        $sheet = $spreadsheet->getActiveSheet();

// 方法二，使用 setCellValue
        //表头
        //设置单元格内容
        $titCol = 'A';
        foreach ($title as $key => $value) {
            // 单元格内容写入
            $sheet->setCellValue($titCol . '1', $value);
            $titCol++;
        }
        $row = 2; // 从第二行开始
        foreach ($data as $item) {
            $dataCol = 'A';
            foreach ($item as $value) {
                // 单元格内容写入
                $sheet->setCellValue($dataCol . $row, $value);
                $dataCol++;
            }
            $row++;
        }

$writer = \PhpOffice\PhpSpreadsheet\IOFactory::createWriter($spreadsheet, 'Xlsx');
        $writer->save('php://output');
        exit;

}
   
   // excel文件读取
   public function read() {
   
       $file = "excel.xls"; // 这里写路径
       $spreadsheet = \PhpOffice\PhpSpreadsheet\IOFactory::load($file);
       $sheet = $spreadsheet->getActiveSheet();

$res = [];
       // 读取excel文件表格
       foreach ($sheet->getRowIterator(1) as $row) {
          $tmp = [];
          foreach ($row->getCellIterator() as $cell) {
             $tmp[] = $cell->getFormattedValue();
          }
         $res[$row->getRowIndex()] = $tmp;
       }

print_r($res);
   }

}

5、访问url，即可下载excel文件

index.php?s=demo&c=excel&m=index
