PHP Security
Views: 37149
1. Introduction
Writing PHP applications is pretty easy. Most people grasp the syntax rather quickly and will within short time be able to produce a script that works using tutorials, references, books, and help forum forums like the one we have here at PHP Freaks. The problem is that most people forget one of the most important aspects that one must consider when writing PHP applications. Many beginners forget the security aspect of PHP. Generally, your users are nice people, they will do as they are told and you will have no problem with these people whatsoever. However, some people are not quite as nice. Some people are outright malicious and are seeking to do damage on your website. They will scrutinize your application for security flaws and exploit these holes. Many times the beginner programmer did not know that these things would even be a problem and therefore it might be a problem to fix the holes. In this tutorial we will look at some of these issues so you can learn how to deal with them, and better yet, prevent them. Obviously I will not promise you that by following this tutorial you will never get successfully attacked. As you become bigger you will also become a bigger and therefore more interesting target - something we have experienced ourselves here at PHP Freaks.
On the next page we will look at how we should do our error reporting.
