Multiple requires

[razorsese]

Currently on my page all my important script is done in 1 page;

I was thinking to break it in multiple php files

So my question is does multiple requires slow down the PHP script?!

I really can't address the speed, but it is common to break things into useable parts to it's easier understand.  Even html parts are often saved as separate sections, eg. require("header.php"); etc.  It's even a good idea in mho to only require "parts" that are needed for a particular page, so doing a simple task doesn't need to scan through a huge processing page to find the matching processing script.

The difference in speed is negligible.

 

Breaking up your script logically into files is a very good idea.

As long as you are not including multiple 100's of files on each page request, you won't have any problem.

 

At least one of the open source (cart) scripts was blindly reading through and including everything in multiple folders, loading 200+ files on each page request (instead of only loading what the page needed) and on the first request after a period of inactivity, since the files weren't in the disk cache, took a noticeable amount of time compared to follow-on requests that were able to read everything from the disk cache.
