I'm relatively new to PHP and currently working on implementing user authentication and authorization in my website. I was wondering how to effectively handle control structures in PHP to ensure secure user access to certain parts of the website.
To give you some background, I have a PHP-based website where users can sign up, log in, and perform various actions based on their roles. I want to make sure that only authorized users can access certain pages or perform certain actions. For example, an administrator should be able to access the admin dashboard, while regular users should only have access to their own profile and limited functionality.
I understand the basic concept of control structures such as if statements, switch cases, and loops, but I'm not sure how to apply them in the context of user authentication and authorization. I want to avoid any potential security loopholes and ensure that control structures are properly integrated with my user management system.
So, my question is: what are some best practices and approaches for handling control structures in PHP when it comes to user authentication and authorization? Are there any specific PHP functions or libraries that can simplify this process? I would appreciate any guidance or examples you can provide.
Thanks in advance for your help!
