    so what do you modify from the last code and to send the user to the index.php (login success page)?

    I just wanted to say thanks for the free tutorials and the quality of them. I was wondering if you might take a look at some code I was working on in PHP. It is a password handler class i was creating to encapsulate a random site-key, secret-key, and salt for each user so it not stored in a database or in a config file. since I am a beginner to intermediate programmer and pretty much new to OOP I know it more than likely can be optimized. I would like your opinion and advice on the code.

    @hotnsexyprince There are few attacks SQL Injection, Cross Site Scripting (XSS), Malicious Code Encoding, Session Hijacking, Session Fixation, Malicious System Calls, Buffer Overflows and DOS attacks. DOS can't be stopped. I have covered everything else except Buffer Overflows. I didn't cover that because the protection methods are kind of complicated. I may cover them in the future. I'm also working on a firewall

    @hotnsexyprince It's kind of amazing. The difference between a good developer and everyone else is their knowledge of security. Barely anyone has seen this video. I'll revisit security in the future. I got in a bit of trouble for posting my other php security videos 🙂

    @MelvinSF I'm glad you like it. I have a nice little community. I don't get more views because I don't really aim to get views. I'm just having fun.

    Over 200 isn't a tiny amount by any means, but I'm surprised these excellent tutorials don't have more views. Great work!
