Question about include

[miles_rich]

Have i set up my directory structure wrong?

I have a functions folder with all my functions in it.

I then have folders with my html and php in it.

When ever i need to use a function i just include that function page into the other pages. but some times i get errors, becuase i use 2 functions pages and the function is already called in that function i get an error, how should i set up my directory structure??

I needed to use the same function twice on the same page (an alternating row class function). I made the function into a class, now i can use as many instances of the class on the same page as i want as each time it is called I can assign a unique name to it.
As for my functions, I have them all on one page (function.php) and I require it at the start of the page.
Hope this helps.
