php issues

I'm in the process of making a content management system for a friend. I realize this code is HORRIBLY inefficient, but at the moment I'm just working with functionality. There are 8 news articles. Each one is stored in a text file. Each article has an accompanying title and image, in its own text file. This script is supposed to shift them down. For example, if I were to post a new article, I was article 7 to become article 8 to make room for the new item. I want the titles and images to shift as well. However, it is not working. Does anyone know why?

PHP:

Why don't you use one textfile for each newsitem and then use explode to read the data?
