Hello,
I've followed the whole series of Log in and registration system on the phpacademy channel on Youtube: http://www.youtube.com/playlist?list=PLE134D877783367C7
After reading some comments and doing some research I found that it uses md5 and old mysql_ function, which for some reason are 'deprecated' or not secure. I'm still not sure. Also, after doing some searching I came across: http://www.sunnytuts.com/article/login-and-registration-with-object-oriented-php-and-pdo which is another tutorial that is quite similar to the one on phpacademy, but it uses PDO and Object oriented programming and bcrypt instead of md5().
The problem is that I don't know OOP and I use procedural programming. So is it worth learning OOP and using bcrypt() instead of md5() or PDO instead of mysql?
I mean, am I ok with using the code from phpacademy, or do I need to follow the other one and also learn OOP.
Thank you very much.
