What are the best practices for handling and manipulating HTML content within a .txt file using PHP?

When handling and manipulating HTML content within a .txt file using PHP, it is important to read the file contents, perform the necessary operations on the HTML content, and then save the modified content back to the .txt file. To achieve this, you can use functions like file_get_contents() to read the file, manipulate the HTML content as needed, and then use file_put_contents() to save the changes back to the file. 

// Read the contents of the .txt file
$html_content = file_get_contents('file.txt');

// Manipulate the HTML content (e.g. add a <div> tag)
$html_content = '<div>' . $html_content . '</div>';

// Save the modified content back to the .txt file
file_put_contents('file.txt', $html_content);
