Is it advisable to use external files and include statements for handling permission checks in PHP applications?

It is advisable to use external files and include statements for handling permission checks in PHP applications to keep the code modular, organized, and easier to maintain. By separating permission logic into external files, it allows for better code reusability and makes it simpler to update permissions without having to modify multiple files. 

// permission_check.php
function checkPermission($userRole, $requiredRole) {
    // Check if user has the required role
    if ($userRole !== $requiredRole) {
        die("You do not have permission to access this page.");
    }
}

// index.php
include 'permission_check.php';

$userRole = 'admin';
$requiredRole = 'admin';

checkPermission($userRole, $requiredRole);

// Rest of the code for the page
