What are the limitations of manipulating office documents using PHP, and how does this affect the development of a file sharing system?

One limitation of manipulating office documents using PHP is that it may not support all file formats or advanced features of certain document types. This can affect the development of a file sharing system as it may restrict the types of files that can be uploaded and shared. To address this issue, developers can use third-party libraries or APIs that offer more comprehensive support for various document formats.

// Example using PHPWord library to manipulate Word documents
require_once 'vendor/autoload.php';

$phpWord = new \PhpOffice\PhpWord\PhpWord();

// Create a new Word document
$section = $phpWord->addSection();
$section->addText('Hello World!');

// Save the document
$writer = \PhpOffice\PhpWord\IOFactory::createWriter($phpWord, 'Word2007');
$writer->save('hello_world.docx');
