Registation PHP

[essellar]

There are a few things I can get pretty cranky about, and home-rolled security is high on that list. It not only puts the users at risk, it also puts the other people using the same server at risk. PHP has a lot of good stuff built into it (especially since 5.5), and the old work-arounds are just too risky to even think about using anymore.

I have to say that SQL injections are VERY dangerous.
You can fill up the max connections/"questions", execute arbitrary queries/shell commands and much more. A major risk for web hosts. People who are going to use these services must know how important this is to protect both their site and server, especially if they're using the service for free.

It's understandable. Functions can quickly become unreliable when vulnerabilities come along, like getimagesize().
