Are there any best practices for including JavaScript code within PHP files to ensure compatibility with different browsers?

When including JavaScript code within PHP files, it is important to ensure compatibility with different browsers. One best practice is to use the `script` tag with the `type` attribute set to `"text/javascript"` to specify that the content is JavaScript. Additionally, it is recommended to use external JavaScript files rather than inline code to improve maintainability and allow for caching. 

<!DOCTYPE html>
<html>
<head>
    <title>Example Page</title>
</head>
<body>
    <?php
    // Include external JavaScript file
    echo '<script type="text/javascript" src="script.js"></script>';
    ?>
</body>
</html>
