PHP . Retrieve link selection values into result page

I want to retrieve selected links values from four different pages and
echo user's selection in Final Page Five (results)
e.g
Computer & Network/Components and Parts In United States / New York
Example
Page 1 ( $Category )
Page 2 ($SubCategory)
Page 3 ( $Country )
Page 4 ( $Province )
Final Page 5 (Results)
Computer & Network (Page1) / Components and Parts (Page2) In United States
(Page3) / New York(Page4)
I want to use <a href""> Link </a> not Submit Button
