How many lines of PHP code is too many for one file?

Question

I\'m creating a PHP file that does 2 mysql database calls and the rest of the script is if statements for things like file_exists and other simple variables. I have about 2000

Answer 1

It really doesn't matter, so long as you have documented your code properly, modularised as much as possible, and checked for any inefficiencies. You may well have a 10,000 line file. Although I usually split at around 500-1000 for each section of an application.
