创建文件composer.json 告诉composer您的项目所依赖的包
注意位置 一定要是你项目的插件位置
文件内容

{
    "require": {
        "phpoffice/phpspreadsheet": "^1.4"
    }
}

用cmd composer 安装 phpoffice/phpspreadsheet 注意位置 一定要是你项目的插件位置

更新composer update

D:\Library> composer update

之后要是添加别的需要用 也是用到 composer update 进行按照进的或者更新

D:\Library> composer update

Ok
创建php文件使用吧

require ‘vendor/autoload.php’;

use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;

$spreadsheet = new Spreadsheet();
$sheet = $spreadsheet->getActiveSheet();
$sheet->setCellValue(‘A1‘, ‘Hello‘);
$sheet->setCellValue(‘A2‘, ‘Hello World‘);
$sheet->setCellValue(‘A3‘, ‘!‘);


$writer = new Xlsx($spreadsheet);
$writer->save(‘hello world.xlsx‘);

?>

默认保存到执行php的根目录，以thinkphp为例index.php在D:\wwwroot\thinkphp\public，那么文件就保存在这
注：如果不想保存到文件，可以传入php://output或php://stdout直接输出（例如html，输出网页）
