What are best practices for incorporating JavaScript functionality in PHP-generated content, considering accessibility and user experience?

When incorporating JavaScript functionality in PHP-generated content, it is essential to ensure accessibility and a positive user experience. One best practice is to separate the JavaScript code from the PHP code to improve maintainability and readability. Additionally, consider using progressive enhancement techniques to ensure that the functionality remains accessible even if JavaScript is disabled. 

<?php
// PHP code to generate content
echo "<div id='content'>PHP-generated content</div>";
?>

<script>
// JavaScript code for functionality
document.getElementById('content').addEventListener('click', function() {
  alert('Content clicked!');
});
</script>
