Question

我正在尝试使用phpspreadsheet库合并多个Excel文件（大约2-10个文件）。我遇到致命错误：第27行，在merge.php中的非对象上调用了__clone方法。不过，我尝试检查所有内容。也许是因为格式？但是将其设置为xlsx。是否可以同时合并xlsx和xls文件？这是我的代码块

<?php

   require 'vendor/autoload.php';

   use PhpOffice\PhpSpreadsheet\Writer\Xlsx;

   $inputFileType = 'Xlsx';
   $inputFileNames = [
     'file1.xlsx',
     'file2.xlsx',
     'file3.xlsx'
   ];
   $sheetnames = [
     'Worksheet',
     'Worksheet1',
     'Worksheet2'
   ];
   $reader = \PhpOffice\PhpSpreadsheet\IOFactory::createReader($inputFileType);
   $reader->setLoadSheetsOnly($sheetnames);
   $inputFileName = array_shift($inputFileNames);
   $spreadsheetMain = $reader->load($inputFileName);
   $spreadsheetMain->getActiveSheet()->setTitle('page0');
   $num = 1;
   foreach ($inputFileNames as $book => $inputFileName) {
      echo ('$inputFileName: ' . $inputFileName) . '</br>';
      $spreadsheet = $reader->load($inputFileName);
      $clonedWorksheet = clone $spreadsheet->getSheetByName('Worksheet'.$num);
      $clonedWorksheet->setTitle('Worksheet'.$num);
      $spreadsheetMain->addExternalSheet($clonedWorksheet);
      $num++;
   }
   $writer = new Xlsx($spreadsheetMain);
   $writer->save('prueba1.xlsx');
?>

By the way this is the link for the code and files I tried to merge.

欢迎任何帮助。谢谢

您似乎正在将电子表格克隆为变量。首先创建一个电子表格对象，然后进行克隆。

/** Create a new Spreadsheet Object **/ $clonedWorksheet = new \PhpOffice\PhpSpreadsheet\Spreadsheet();

使用PHPSpreadSheet库在PHP中合并Excel文件
