How can PHP be integrated with HTML5 and JavaScript to create a progress bar for file uploads?

To create a progress bar for file uploads using PHP, HTML5, and JavaScript, you can utilize AJAX to send the file data to the server and track the upload progress. PHP will handle the file upload process, while HTML5 and JavaScript will update the progress bar in real-time. 

```php
<?php
if ($_SERVER['REQUEST_METHOD'] === 'POST' && isset($_FILES['file'])) {
    $file = $_FILES['file'];
    $targetDir = 'uploads/';
    $targetFile = $targetDir . basename($file['name']);

    if (move_uploaded_file($file['tmp_name'], $targetFile)) {
        echo json_encode(['success' => 'File uploaded successfully']);
    } else {
        echo json_encode(['error' => 'Failed to upload file']);
    }
    exit;
}
?>
```
This PHP code snippet handles the file upload process.
