php 管理权限

<?php
// 假设有一个用户类 User 和一个权限类 Permission
class User {
    private $role;

    public function __construct($role) {
        $this->role = $role;
    }

    public function getRole() {
        return $this->role;
    }
}

class Permission {
    private $permissions = [
        'admin' => ['access_admin_page', 'edit_users'],
        'user' => ['access_user_page']
    ];

    public function canAccess($role, $permission) {
        return isset($this->permissions[$role]) && in_array($permission, $this->permissions[$role]);
    }
}

// 使用示例
$user = new User('admin');
$permission = new Permission();

if ($permission->canAccess($user->getRole(), 'access_admin_page')) {
    echo "Access granted to admin page.";
} else {
    echo "Access denied.";
}
?>
