Hi there, I'm Arturo, I'm a newbie and that's why I'm asking for some help, let's begin, I've to start a project in PHP, basically there's just 2 users and admin and the rest of the sales department, the admin functions are to create new users, view their details, their customers details ( name, lastname, email, status ), delete users and change users details, the users can just log in and check only their details, for example is there's 2 users, user "a" and user "b", the user "a" just can check his details not the user "b" details, their customers information, add new customers, modify customers status and details, well, the problem here is as I said before, I'm a newbie and don´t know how to do this and I've some rush, so, do you guys know where I can find a Tutorial explaining this kind of functions?, hope somebody here can help me, thanks a lot and sorry for my English!!!
