What are the best practices for integrating PHP and JavaScript functionalities in a web application?

When integrating PHP and JavaScript functionalities in a web application, it is important to understand the differences between server-side and client-side scripting. One common approach is to use PHP to generate dynamic content and then use JavaScript to manipulate that content on the client-side. This can be achieved by sending data back and forth between PHP and JavaScript using AJAX calls or by embedding PHP variables directly into JavaScript code. 

<?php
// PHP code to generate dynamic content
$dynamic_content = "Hello, World!";
?>

<script>
// JavaScript code to manipulate dynamic content
var dynamicContent = "<?php echo $dynamic_content; ?>";
console.log(dynamicContent);
</script>
