What potential pitfalls should be considered when implementing a switch function in template files?

When implementing a switch function in template files, it is important to consider the potential pitfalls of using switch statements, such as code duplication, difficulty in maintenance, and scalability issues. To address these concerns, it is recommended to use a more flexible and maintainable approach, such as creating separate template files for each case and including them dynamically based on the switch condition.

<?php
switch ($variable) {
    case 'case1':
        include 'template_case1.php';
        break;
    case 'case2':
        include 'template_case2.php';
        break;
    default:
        include 'default_template.php';
        break;
}
?>
