How can a PHP developer efficiently manage CSS and JavaScript resources in a MVC architecture to avoid HTML validation errors?

In order to efficiently manage CSS and JavaScript resources in a MVC architecture to avoid HTML validation errors, a PHP developer can use a templating system to separate the presentation layer from the business logic. By using a templating system, the developer can include CSS and JavaScript files in the appropriate template files, ensuring that they are only loaded when needed and reducing the risk of validation errors.

// Example of including CSS and JavaScript files in a template file
<!DOCTYPE html>
<html>
<head>
    <title>My Website</title>
    <link rel="stylesheet" type="text/css" href="<?php echo $css_path; ?>/styles.css">
</head>
<body>
    <h1>Welcome to my website</h1>
    
    <script src="<?php echo $js_path; ?>/script.js"></script>
</body>
</html>
