PhP Simulation Script Using Conditional Statements.

Last Updated on: May 5, 2013

This script simulates a dog moving to its kennel. It consists of all conditional statements except switch. Initially we set to random positions for the dog and the kennel using the php function rand(). We set up the position using the x, y cordinates. Here i have used a 10X10 square. you can check out the script given below. You can see the demo here. Simulation Demo
