Is it advisable to handle large file uploads using PHP directly, or should an external program be used instead?

Handling large file uploads directly in PHP can lead to memory and performance issues, especially when dealing with files over a certain size limit. It is advisable to use an external program or library, such as Dropzone.js or Fine Uploader, to handle large file uploads more efficiently and securely. These tools can help break down the file upload process into smaller chunks, handle file validation, and provide progress indicators to the user. 

```php
// Example using Dropzone.js for handling large file uploads
<!DOCTYPE html>
<html>
<head>
  <title>Large File Upload</title>
  <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/dropzone/dist/min/dropzone.min.css">
</head>
<body>
  <form action="upload.php" class="dropzone"></form>
  <script src="https://cdn.jsdelivr.net/npm/dropzone"></script>
</body>
</html>
```

In the `upload.php` file, you can then handle the file upload using Dropzone.js and process the uploaded file accordingly.
