phpoffice在tp框架中如何实现导入导出功能

安装 phpoffice/phpspreadsheet 库

composer require phpoffice/phpspreadsheet

导入功能

创建一个用于上传文件的视图，可以使用元素来实现文件上传。

<!-- application/view/your/import.html --><form action="{:url('your/import')}" method="post" enctype="multipart/form-data"><input type="file" name="file"><button type="submit">导入</button>
</form>

导入逻辑

// application/controller/YourController.phpnamespace app\controller;use PhpOffice\PhpSpreadsheet\IOFactory;class YourController
{public function import(){if ($this->request->isPost()) {$file = $this->request->file('file');// 检查文件是否上传成功if ($file) {// 获取上传文件的临时路径$filePath = $file->getRealPath();// 读取 Excel 文件$spreadsheet = IOFactory::load($filePath);// 处理 Excel 数据// 例如：遍历行和列，保存到数据库} else {// 文件上传失败return '文件上传失败';}}return $this->fetch('your/import');}
}

导出功能

// application/controller/YourController.phpnamespace app\controller;use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;class YourController
{public function export(){// 创建新的 Excel 对象$spreadsheet = new Spreadsheet();// 在这里添加数据到 Excel// 保存 Excel 文件$writer = new Xlsx($spreadsheet);$filename = 'exported_data.xlsx';header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');header('Content-Disposition: attachment;filename="' . $filename . '"');header('Cache-Control: max-age=0');$writer->save('php://output');}
}

在路由中配置

// application/route/route.phpuse think\facade\Route;Route::get('your/import', 'YourController/import');
Route::post('your/import', 'YourController/import');
Route::get('your/export', 'YourController/export');
