You appear to be using the GET method, perhaps POST is in order.  

One of php's coolest features is its ability to handle form fields as
arrays.  

name your fields with a [], such as field1[], and it will return an
array with one or more elements.  Look at
http://www.php.net/manual/en/language.variables.external.php  and try it
out.

Note that this can also be handy to separate different sections of the
form as well:

address[street][]
address[street][]
address[city]
address[state]
...

and don't forget to use print_r to see what you got back!
