The world is changing. While that is not bad for small forms or simple tasks but what if your project is larger or lets just say after reading this article you abondon gathering all the $_GET data from your simple form?

He goes on to talk about the different flags that you can pass in for various options (like "overwrite existing variable" or "prefix variable names with this" sorts of things). Of course, this kind of methodology has to be used carefully so as not to create more security issues than it's worth...
