What are some alternative methods to convert XLS and DOC files to HTML without using COM in PHP?

One alternative method to convert XLS and DOC files to HTML without using COM in PHP is to use third-party libraries such as PHPExcel and PHPWord. These libraries provide functions to read XLS and DOC files and convert them to HTML format. By utilizing these libraries, you can achieve the conversion without relying on COM objects.

// Include the PHPExcel library
require_once 'PHPExcel/Classes/PHPExcel.php';

// Load the XLS file
$objPHPExcel = PHPExcel_IOFactory::load('example.xls');

// Save the XLS file as HTML
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'HTML');
$objWriter->save('example.html');
```

```php
// Include the PHPWord library
require_once 'PHPWord/PHPWord.php';

// Load the DOC file
$phpWord = new PHPWord();
$document = $phpWord->loadTemplate('example.docx');

// Save the DOC file as HTML
$document->save('example.html', 'HTML');
