PHP

Welcome to part 2, if you didn’t read part 1, please do, because this is a continuation of that. Now we want to go a step further and add “First” and “Last” links to our navigation.
“First” should point to the first page of our result set and last should point to the last page.

Lets say you got a site that prints out some result based ona search or lists some items and it has hundreds of rows. Therefore, you end uphaving a lengthy list, which is hard to read. If your list contains images,Hundreds of images get loaded on a single page. This is not appealing. I’mgoing to show you a way of dividing results into several pages and allow usersto navigate through there results.

I'm going to show you how you can allow users to upload file into your web server. I'm just covering the basics here. Though I'm not concerning security related issues here, there is a big risk in allowing users to upload files.
The first reason is that people can upload scripts into you server and execute them there. The second easiest thing to do is write a script that upload hundreds of thousands of files into your server, eventually making it run out of disk space. Hopefully in the future I'm going to write some security articles as well.
