What are some best practices for ensuring compatibility with multiple browsers when using PHP and JavaScript together?

To ensure compatibility with multiple browsers when using PHP and JavaScript together, it is important to use feature detection rather than browser detection. This involves checking for the availability of specific browser features before executing JavaScript code. Additionally, using polyfills or fallbacks for unsupported features can help maintain functionality across different browsers. 

<?php
// Check if the browser supports a specific feature before executing JavaScript code
echo '<script>';
echo 'if (window.localStorage) {';
echo '  // Your JavaScript code that relies on localStorage';
echo '}';
echo '</script>';
?>
