What are some common challenges faced when saving form data to an HTML file in PHP?

One common challenge when saving form data to an HTML file in PHP is handling file permissions. Make sure the directory where you are saving the file has the correct permissions set to allow PHP to write to it. Another challenge is properly formatting the data before writing it to the file, such as escaping special characters to prevent injection attacks. Lastly, ensure that the file path is correctly specified in the PHP code to save the file in the desired location. 

<?php
// Set the file path
$file_path = 'data/form_data.html';

// Check directory permissions
if (!is_writable(dirname($file_path))) {
    die('Directory does not have write permissions');
}

// Get form data
$form_data = $_POST['form_data'];

// Format the data
$formatted_data = htmlspecialchars($form_data);

// Save data to the file
file_put_contents($file_path, $formatted_data);
?>
