This suite shows a typical usage of sessions through a sequence of 4 pages : 1.php → 2.php → 3.php → 4.php
The scenario is the following :
You are going to report to the main Headquarter of your company the recommendations of new personnel selection.
So you start filling the data in page 1.php (this) ...transport the data to page 2.php ... add data in page 2.php ... transport the data to page 3.php and check the entire list , , , if that satisfies you, then send the report to your Headquarter by processing file 4.php, otherwise you get back to previous pages and make the allowed corrections.
Data are transported page by page in sequence by the session's registered variables.
Suppose then you just want to re-start resuming, then you can destroy the session in any moment and be re-addressed to 1.php as it is exemplified in file 3.php :-)
