"Caching" a php script

PHP
1

Hello,

In javascript, CSS, the browser can cache files so that there are fewer trips to the browser. Might there be something analogous in PHP? In particular, to keep organized, I have every function that I need for my site in one script. Each script only calls a few functions and it seems a bit of a waste of resources to read through the entire script each time. So, is it possible to either:

  1. Create “Session Functions” that can be defined once and then used while a user is logged in
  2. Somehow Cache the functions

If neither works, then I can definitely break the functions script into smaller pieces, but I’d much prefer to leave things as is if possible.

Thank you,

Eric

It sounds like you’re looking for a PHP Accelerator. There’s quite a few of those out there. The most popular ones are APC and XCache AFAIK.

There’s an explanation of PHP Accelerators with a nice list over at wikipedia, here List of PHP accelerators - Wikipedia, the free encyclopedia

Exactly what I’m looking for! Thanks so much…

APC becomes part of PHP core as of 5.4, so unless you specifically need a function out of one of the other accelerators I would recommend learning and using it.
