Investigating PHP
I am currently working my way through MySQL for Dynamic Websites by Larry Ullman (edition 4).
I currently (as at December 2012) run php 5.3.10-10 and a mysql 5.1.28 database on apache 2.2.22 server on Ubuntu 12.04 in VirtualBox.
Chapter 13: Review and Pursue
Update to chapter 3 calculator.php that works out details for a car journey: Mar 2013
The php code in the pdf below is an investigation of the 3rd Review element of Chapter 13 PHP and MYSQL for Dynamic Web Sites (ed4) by Larry Ullman.
Changed this to add filter_var function to validate the input. There's quite a lot going on here mostly as solutions to the ch3 Review and Pursue.
