if(hasPermission($user, 'access_page')) { // allow access to restricted page } else { // redirect user to login page or display error message }
if(hasPermission($user, 'delete_post')) { // allow user to delete post } else { // display error message - "You do not have permission to delete this post" }The hasPermission function is commonly used in PHP frameworks like Laravel and Symfony, where it is part of the authorization package or library. However, it can also be implemented as a custom function or part of a separate authorization library.
