二，编写php代码

1,类库

lib/util/excel.php

<?php
namespace app\lib\util;
 
use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;
 
class excel {
 
    /*
     * 把导出为excel到浏览器并下载
     * $title:标题
     * $headArr: 表头
     * $data: 数据
     * $fileName:文件名
     * */
    function excelExport($title="",$headArr = [], $data = [],$fileName = '') {
        $fileName       .= "_" . date("Y_m_d", time()) . ".xls";
        $spreadsheet    = new Spreadsheet();
 
        $objPHPExcel    = $spreadsheet->getActiveSheet();
        $objPHPExcel->setTitle($title);
        $objPHPExcel->setCellValueByColumnAndRow(1, 1, $title);
        // 设置表头
        $key = ord("A"); 
        foreach ($headArr as $v) {
            $colum = chr($key);
            $objPHPExcel->setCellValue($colum . '1', $v);
            $key += 1;
        }
 
        $column = 2;
        foreach ($data as $key => $rows) { // 行写入
            $span = ord("A");
            foreach ($rows as $keyName => $value) { // 列写入
                $objPHPExcel->setCellValue(chr($span) . $column, $value);
                $span++;
            }
            $column++;
        }
 
        header('Content-Type: application/vnd.ms-excel');
        header('Content-Disposition: attachment;filename="' . $fileName . '.xlsx"');
        header('Cache-Control: max-age=0');
        $writer = new Xlsx($spreadsheet);
        $writer->save('php://output');
        //删除临时的sheet
        $spreadsheet->disconnectWorksheets();
        unset($spreadsheet);
        exit;
    }
}

2,在controller中调用:

controller/Article.php

use app\lib\util\excel;
class Article extends BaseController
{
    //导出为excel文件
    public function excel() {
        $fileName="2022年员工名单";
        $title="2022年员工名单";
        $headArr = ['id', 'name', 'sex'];
        $data = [
            [1,'老刘','男'],
            [2,'老马','女'],
            [3,'小刘','男'],
            ];
        $excelObj = new excel();
        $excelObj->excelExport($title, $headArr, $data,$fileName);
    }
}

三，测试效果

1,访问:

http://192.168.219.6:8000/article/excel

2,查看导出的文件:

四，查看php和thinkphp的版本:
