How can one ensure that the correct file is loaded based on user input in PHP scripts?

To ensure that the correct file is loaded based on user input in PHP scripts, you can use conditional statements to check the user input and include the corresponding file. This can help prevent errors and ensure that the correct functionality is executed based on the user's choice. 

$user_input = $_GET['file'];

if ($user_input === 'file1') {
    include 'file1.php';
} elseif ($user_input === 'file2') {
    include 'file2.php';
} else {
    // Handle invalid input or provide a default file to load
    include 'default.php';
}
