[PHP] redirecting some values from one page to other in php

[babu]

I am using header method for redirecting to another php file.I also want to 
pass some variables to the redirected file.

for example:

file1.html---- where i have a dropdown menu. the user selects the options... 
this form  has a action to file2.php
file2.php--- i get the values of the form by using $_POST. In this file i will 
do some processing  on data and redirect to file3.php
file3.php---- here i need the user select menu items.

i think i can use require_once(file2.php) in file3.php and get the values.But i 
want to get the values selected by user from html form.

Thanks for the help.
