I'm not very familar with PHP in terms of code writing, so I'm curious about something.

On my website, www.bui4ever.com, I'm using <? include('name of document.txt'): ?> in place of where I change information frequently. I then input the information into a text document and link it to that line. I do it so when I alter the text, I don't have to risk messing with the layout. Is there any forseeable problems I may run into in the future doing it this method? I don't really need a database or anything fancy like that. Thanks!
