What are the best practices for integrating HTML, Javascript, and PHP to avoid syntax errors and ensure smooth functionality?

To avoid syntax errors and ensure smooth functionality when integrating HTML, JavaScript, and PHP, it is essential to properly separate the different languages within the code. One common best practice is to use PHP to generate dynamic content and JavaScript for client-side interactivity. To prevent syntax errors, make sure to properly escape characters and use consistent coding conventions. 

<?php
// PHP code to generate HTML with embedded JavaScript
echo '<html>';
echo '<head>';
echo '<script>';
echo 'function myFunction() {';
echo 'alert("Hello World!");';
echo '}';
echo '</script>';
echo '</head>';
echo '<body>';
echo '<button onclick="myFunction()">Click me</button>';
echo '</body>';
echo '</html>';
?>
