How can PHP arrays be utilized to streamline permission checks and avoid nested if statements?

When dealing with permission checks, using PHP arrays can streamline the process by mapping permissions to specific roles or users. This allows for easier management of permissions and avoids the need for nested if statements. By storing permissions in an array and checking against it, you can quickly determine if a user has the necessary permissions without complex logic. 

// Define permissions array
$permissions = [
    'admin' => ['create', 'read', 'update', 'delete'],
    'editor' => ['create', 'read', 'update'],
    'viewer' => ['read']
];

// Check if user has permission
$userRole = 'editor';
$requestedPermission = 'update';

if (in_array($requestedPermission, $permissions[$userRole])) {
    echo "User has permission to $requestedPermission";
} else {
    echo "User does not have permission to $requestedPermission";
}
