PHP code - HTML questions

Not sure if anyone can help me, but i have a web developer who left our company recently.  He had developed a web store / ordering system that would produce sales order and then via a ODBC connection we would extract our orders from the web to our business application.

I have a process in the system by which you can select a item, and add it to the cart, the item has:
Item Code   xxxxxx
Weight 6
Quanity 1

in checking to see how much the freight is on the order we use the Customer Header info to check to see how much shipping is to ship that item or items, using the customer zip code, order weight, and country.

Well I have removed all the weight off the item that I like to give free shipping to but if you order just 1 item and it is to get free shipping the system SOMEWHERE has a default value for any shipment.
I found in one of the PHP programs a value for Minimum and set it to '0.00', expecting to see that because the order weight is 0lb it would not calculate freight,  this failed and the default value changed  I then found in our shipping table a handling fee, fuel rate and ofther fee's.  I changed all those to 0,and still the system is finding a value some where for calculation of our shipping cost.

Well after this lengthy review, I have been able to trace it back using the URL program...but I cannot find the program associated to the URL.
So when i see the URL   xxx.xxxxxxxx.com/calculate-shipping,

I am not sure how this is converted, is there a main program which controls the urls so that they are hidedn?

I see PHP files that are close to the same name but not exactly.

Question 1 can i identify the correct program using the URL?
Question 2 also if there are session variable being used how can i display their contents?

Again, this m ay not be anything someone can answer without reviewing the actual data?

Unfortunately there could be a hundred different ways of calulating the shipping and a URL does not always relate to a single file - a URL could relate to a Controller in an MVC set up, or be re-written using an htaccess file.

Without seeing your app, it's going to be very difficult to guess.

I completely understand.  I got it traced back to coding I do not understand, yet?
I am working on it, but since I had someone else develop and the documentation is por, I am having a problem following the code...
Need a expert...
Thanks

$html .= "<ul class=\"sided\"><li><a href=\"/calculate-shipping\" style=\"font-size:0.9em;\" ".
            "title=\"Go to calculate shipping and handling\">Get shipping cost</a></li>";

Probably somewhere in the code the shipping is being set to a default value if no value exists or the value is 0
As Chris said we can only guess
Is there a page or a folder called calculate-shipping? Attach that here

calculate-shipping could be any number of things - it doesn't necessarily represent a physical file.

It could be a module, a controller, a function, it could be re-written to a completely different file, it may just be an anchor for javascript to hook into.

Unfortunately, it's impossible to tell from seeing a small snippet of HTML. These things don't work in isolation - they're all a part of the whole project.
