Are there best practices or guidelines for handling user permissions and roles in PHP applications to avoid issues with administrator rights?

When handling user permissions and roles in PHP applications, it is important to follow best practices to avoid issues with administrator rights. One common approach is to use role-based access control (RBAC) where each user is assigned a role with specific permissions. By properly defining roles and permissions, you can ensure that administrators have the necessary rights without granting excessive privileges to regular users. 

// Example of implementing RBAC in PHP

// Define roles and their corresponding permissions
$roles = [
    'admin' => ['manage_users', 'manage_content'],
    'editor' => ['manage_content'],
    'user' => []
];

// Check if a user has permission to perform a certain action
function hasPermission($role, $permission) {
    global $roles;
    return in_array($permission, $roles[$role]);
}

// Example usage
$userRole = 'admin';
if (hasPermission($userRole, 'manage_users')) {
    echo 'User has permission to manage users';
} else {
    echo 'User does not have permission to manage users';
}
