How can one determine the correct PHP file to include before the inclusion process?

Before including a PHP file, you can determine the correct file to include by using conditional statements based on certain conditions or variables. This can help ensure that the correct file is included dynamically based on the context of your application. 

if ($condition1) {
    include 'file1.php';
} elseif ($condition2) {
    include 'file2.php';
} else {
    include 'default.php';
}
