Paypal PDT Return URL Parsing

[Matt1998]

Hiya, I'm really stumped :/

I have managed to grab the PDT paypal return URL (this could be any url with many query strings contained) - here is a sample of one i'm having problems with, but could be any URL with random names & values:-

http://www.mysite.com/submit_me.asp...country=BE payment_gross=59.29 shipping=0.00

Ok, now that's a bit of a mouthful and i can decode it etc... format it etc... but i'm having a nightmare being clever with it! - I want to dynamically add this to a database... the problem is this >>>item_number=<<< there can be multiple items (i.e. item_number1=) and corresponding descriptions with the same naming conventions.

I need to be able to dynamically write fields that *don't* currently exist into a database from the returned data and i'm lost how to do it... there could be 10+ items brought and paypal throws very weird data back so i want the database to be able to go (in pseudo code)

'split all the names and their variables - or make the name into a variable and assign it its value.

'add this data to a database

'if field does not exist then add it and the corresponding value

that's it!

I've tried a few while loops of the net but i think they've been .net ones...

Help!
