在 phpspreadSheet 中设置具有日期格式的单元格

Question

我正在尝试以这种方式在 xslx（它只是一个测试脚本）文件中设置一些具有日期格式的单元格

<?php
    require 'vendor/autoload.php';

    use PhpOffice\PhpSpreadsheet\Spreadsheet;
    use PhpOffice\PhpSpreadsheet\Writer\Xlsx;
    \PhpOffice\PhpSpreadsheet\Cell\Cell::setValueBinder( new \PhpOffice\PhpSpreadsheet\Cell\AdvancedValueBinder() );

    $spreadsheet = new Spreadsheet();
    $sheet = $spreadsheet->getActiveSheet();
    $sheet->setCellValue('A2',2);
    $sheet->setCellValue('A3',3);
    $sheet->setCellValue('A4',4);
    $sheet->setCellValue('A5',5);

    $time = gmmktime(0,0,0,12,31,2008);
    $sheet->setCellValue('B2', \PhpOffice\PhpSpreadsheet\Shared\Date::PHPToExceldate($time));
    $sheet->setCellValue('B3', \PhpOffice\PhpSpreadsheet\Shared\Date::PHPToExceldate($time));
    $sheet->setCellValue('B4', \PhpOffice\PhpSpreadsheet\Shared\Date::PHPToExceldate($time));
    $sheet->setCellValue('B5', \PhpOffice\PhpSpreadsheet\Shared\Date::PHPToExceldate($time));

    $writer = new Xlsx($spreadsheet);

    if(file_exists('prueba.xlsx'))
        unlink('prueba.xlsx');


    $writer->save('prueba.xlsx');

但我收到此错误消息

致命错误：在第 16 行调用 C:\xampp\htdocs\prueba_excel\index.php 中未定义的方法 PhpOffice\PhpSpreadsheet\Shared\Date::PHPToExceldate()

我已经包含了自动加载文件，我有什么遗漏吗？

您需要将 use PhpOffice\PhpSpreadsheet\Spreadsheet; 放在 php 脚本的顶部，这样：

<?php
use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;
