Serial communication with PHP

Honesly, you're blowing my mind.
I have more experience coding with Visual Basic 6 than I have in any other language/synax. I'm used to using VB, so I declare almost everything as Integers. I've never written any code that was so involved as to worry about size or memory constraints.

On that note, I know I didn't answer your question. I'm not sure why the integer data type worked here or why I didn't use a lesser data type. I just did what I was used to.

I'm open to others' input here as well. Can anyone inform me/us?
