How can PHP be used to restrict access to executable files for specific users on a website?

To restrict access to executable files for specific users on a website using PHP, you can check the user's credentials before allowing them to download or execute the file. This can be achieved by verifying the user's login status and permissions against a list of authorized users or roles. 

<?php
// Check if the user is logged in and has the necessary permissions
if ($loggedIn && $userRole === 'admin') {
    // Serve the executable file
    header('Content-type: application/octet-stream');
    readfile('path/to/executable/file.exe');
} else {
    // Redirect or display an error message
    echo 'You do not have permission to access this file.';
}
?>
