Not only is multiple storage wasteful, but it multiplies your effort if you want to change, especially if you have to go hunting through several files to find where the numbers are defined.Multiple representations are also a great way to generate bugs if you forget to change some of them.
Test as you write As much as possible, test your code as you write it.
These tests will often be quick and easy ones, such as checking that the value of pi you’re using is really what it should be, but if you perform these little checks while you’re working on (and thinking about) that piece of code, you’ll save yourself a lot more effort having to come back later and fix bugs.
You’ll find that you can perform a lot of simple tests very quickly as you go along; once you’re in the habit, you really don’t spend a lot of time doing it.
But the time you save yourself later on can be considerable.
Coding principles helps you to maintain good coding practice along with concrete product development.
Coding principles also helps you write excellent quality of code with huge difference to overall performance and scalability of your application.
Following are the most important Coding Principles which can save a lot for you when you are writing quality application for you or your client.Ensuring these coding principles you can save development time, management time and conquer lots of other bottlenecks which generally arise in later development phases.You can also use the idea of PHP Design patterns which can speed up the development process by providing tested, proven development paradigms.This article is taken from two articles at programming4with few modifications.Don’t Repeat Yourself (DRY) The concept here is that anything you use in your code should have a single, unambiguous representation.This means if you are storing a number, only store it in a single place (don’t have PI stored in three different places).
