php - 如何修复 laravel 5.4 中的警告 Illegal string offset？

Question

我是 laravel 的新手，我想使用 wordphp 包编辑一个 word 文档。

为了尝试它，我保留了互联网上的现有代码，但是一旦我运行它，我就得到了这个错误:

(1/1) ErrorException
Illegal string offset 'w:compatSetting'
in Settings.php (line 173)
at HandleExceptions->handleError(2, 'Illegal string offset \'w:compatSetting\'', 'C:\\wamp\\www\\Stage_2\\vendor\\phpoffice\\phpword\\src\\PhpWord\\Writer\\Word2007\\Part\\Settings.php', 173, array('compatibility' => object(Compatibility)))
in Settings.php (line 173)

这是我的功能编辑 类 editWordController :

public function edit(){

  $phpWord = new \PhpOffice\PhpWord\PhpWord();
  $section = $phpWord->addSection();
  $section->addText(
    '"Learn from yesterday, live for today, hope for tomorrow. '
    . 'The important thing is not to stop questioning." '
    . '(Albert Einstein)'
    );

$section->addText(
  '"Great achievement is usually born of great sacrifice, '
  . 'and is never the result of selfishness." '
  . '(Napoleon Hill)',
  array('name' => 'Tahoma', 'size' => 10)
  );

$fontStyleName = 'oneUserDefinedStyle';
$phpWord->addFontStyle(
  $fontStyleName,
  array('name' => 'Tahoma', 'size' => 10, 'color' => '1B2232', 'bold' => true)
  );

$section->addText(
  '"The greatest accomplishment is not in never falling, '
  . 'but in rising again after you fall." '
  . '(Vince Lombardi)',
  $fontStyleName
  );

// Adding Text element with font customized using explicitly created font style object...
$fontStyle = new \PhpOffice\PhpWord\Style\Font();
$fontStyle->setBold(true);
$fontStyle->setName('Tahoma');
$fontStyle->setSize(13);
$myTextElement = $section->addText('"Believe you can and you\'re halfway there." (Theodor Roosevelt)');
$myTextElement->setFontStyle($fontStyle);
// Saving the document as OOXML file...
$objWriter = \PhpOffice\PhpWord\IOFactory::createWriter($phpWord, 'Word2007');
try {
  $objWriter->save(storage_path('helloWorld.docx'));
}catch(Exception $e)
{}
return reponse()->download(storage_path('helloWorld.docx'));
}

这个错误是什么意思，我该如何解决？

vendor/phpoffice/phpword/src/PhpWord/Writer/Word2007/Part/Settings.php

$this->settings['w:compat']['w:compatSetting'] = array('@attributes' => array(
   'w:name'    => 'compatibilityMode',
   'w:uri'     => 'http://schemas.microsoft.com/office/word',
   'w:val'     => $compatibility->getOoxmlVersion(),
));

替换为这段代码

$this->settings['w:compat'] = array('@attributes' => array(
   'w:name'    => 'compatibilityMode',
   'w:uri'     => 'http://schemas.microsoft.com/office/word',
   'w:val'     => $compatibility->getOoxmlVersion(),
));

这对我有用
