Functions.php & how it relates

rwoody

I'm brand new to PHP/MYSQL and I'm working on modifying an existing app. So far I've managed to struggle through and get alot done. I've read alot of the tutorials, mostly as they applied to pieces that I was working on at the time and have been pretty successful with that. However, if someone would be so gracious and explain to me a bit of the general structure regarding develping within this app's structure (I'll explain briefly) the app has a primary functions.php page. All the functions are listed in this file which is about 15,000 lines of code. But they are very clearly spelled out. I have a reasonablly good understanding of how the functions are built in relationship to the app. Here is my confusion. I want to build a couple brand new functionalities to the app. When I look at the php/html pages I'm just not sure how the php code there is calling the function or even how that process works. I guess my question is, if I create a function in the functions.php how "exactly" do I refer to in the php code. I've probably not done a good job of explaining myself here. But maybe its a start.

Any help would be greatly appreciated.

where does the code

include('./some dir movement/functions.php')

or one of these

include_once(' ')
require(' ')
require_once(' ')

appear?

That is what is confusing to me. Not all functions, as a matter of fact only a few of the functions have an "includes" or a "require". There are over 200 functions written in the file and only 10 of the functions that includes and/or requires referenced at the end of the function. When the function does include one of those, it is generally at the end of the function code. Example:

// SEND THE CUSTOMER NEW ORDER EMAIL
if (setup("email_12") == Y) {
send_mail("12",$account_id,"",$order_id,"");
}
include("member_order_approved.html");
update_all_directory();

I use an excellent PHP editor, so I can readily see all the functions, includes etc for reference.

Thank you so much for helping this newbie understand the process. I believe if I can get this through my thick head I'll will be able to complete the mods. I only have 3 or 4 at the most left and they shouldn't be hard, but I'm just stuck due to not understanding the process flow.
