I'm not new to the PHP scene, I'm just not up to par with the language standards. I've recently stumbled upon a new style called OOP.
Anyways I have a few issues with my current script. I plan on expanding it but started with a "simple" script. My issues:
1. I'm unable to use $this->username in functions like "check_password" ideally I'd like to have it: function check_password() and it'd do $this->username, $this->password. The username/password would be set in the code (like below) but when attempted it just displays null. I've read online that I have to use magic functions as in __get or __set. I also want this to be as dynamic as possible so setVar($var) { $this->username = 'username'; } would not be feasible either.
2. In the function info() I want it to return whatever the request variable is .. right now it's only returning username. I'd assume it'd be something like $row->[$request]
Any help / links to any resources would be highly appreciated. Feel free to suggest alternatives to this current code as I'm still not sure this is the best way to go about things.
