How can the readability and maintainability of PHP-generated HTML code with JavaScript functions be improved?

The readability and maintainability of PHP-generated HTML code with JavaScript functions can be improved by separating the PHP logic from the HTML markup. This can be achieved by using a templating engine like Twig or Blade to keep the PHP code separate from the HTML structure. Additionally, using external JavaScript files for functions instead of embedding them directly in the HTML can make the code easier to read and maintain. 

<?php
// PHP logic
$data = ['name' => 'John', 'age' => 30];

// Render HTML using a templating engine like Twig
echo $twig->render('template.html', ['data' => $data]);
?>
