Excel エクスポートに Hyperf フレームワークを使用する方法

composer require phpoffice/phpspreadsheet

namespace AppUtils;

use PhpOfficePhpSpreadsheetSpreadsheet;
use PhpOfficePhpSpreadsheetWriterXlsx;

class ExcelExporter
{
    public static function export($data, $fileName, $headers, $title = null)
    {
        // 创建Excel对象
        $spreadsheet = new Spreadsheet();
        
        // 设置工作表名称
        $worksheet = $spreadsheet->getActiveSheet();
        $worksheet->setTitle($title ?: 'Sheet1');

        // 写入表头
        foreach ($headers as $key => $header) {
            $column = chr(65 + $key); // 列名，如A、B、C...
            $worksheet->setCellValue($column.'1', $header);
        }

        // 写入数据
        $row = 2; // 数据行起始行号
        foreach ($data as $item) {
            foreach ($item as $key => $value) {
                $column = chr(65 + $key); // 列名，如A、B、C...
                $worksheet->setCellValue($column.$row, $value);
            }
            $row++;
        }

        // 导出Excel文件
        $writer = new Xlsx($spreadsheet);
        $writer->save($fileName);
    }
}
