PHP - Functions, Functions And More Functions -> Timeout!

I have a script I am putting together that simulate a cricket game. The only issue is, that there are a huge number of functions because there doesn't seem to be any other way to do this properly. As well as this, there a while() loop and all this seems to be leading to the page reaching a max 30 second timeout when generating the result.

My code is attached below, it is quite messy at the moment because i've just be working on it, but I was wondering if anyone has any solutions of how I can speed this up or change to prevent a timeout:
