Refactoring is a process of simplifying the code of a PHP program thereby making easy to understand and also faster to execute. It is a technique of developing globally accepted, confusion-free code with minimum alterations such that external behavior of the code remains unchanged.
Refactoring in PHP is a technique of developing easily understandable and confusion-free code for developing applications using this popular programming language. Refactoring is a practice of restructuring the code of a complex program in PHP while taking care that its behavior remains unaltered. In this process no updating processes like adding of new functionalities, fixing glitches etc are performed. Only with basic structure alteration, the complex code is converted into universally accepted simple and easy-to-understand format.
In PHP coding there are different ways to develop an application through different methods. However, all methods are not efficient enough. An easy way to develop a good application is by using simple coding techniques that make execution easier and much faster for the code. This can be achieved through refactoring.
Consider an example of a code written for displaying integer or digit value (taken as input) in words.
Code before refactoring
<?
function display($value)
{
if($value==0) $t = “Zero”;
elseif($value ==1) $t = “One”;
elseif($value ==2) $t = “Two”;
elseif($value ==3) $t = “Three”;
elseif($value ==4) $t = “Four”;
}
?>
Code after refactoring
<?
function DisplayInputValueInText($digit)
{
switch($digit)
{
case 0: echo “Zero”;break;
case 1: echo “One”;break;
case 2: echo “Two”;break;
case 3: echo “Three”;break;
case 4: echo “Four”;break;
}
}
?>
So code refactoring is greatly beneficial both to the programmers as well as the readers as it makes coding easy as well as makes the code easily understandable for the reader as well.
Code refactoring techniques can best be learnt in PHP training classes under the guidance of programming experts who have the best knowledge of implementing them. Hence, for those looking to become good PHP developers should PHP training under experts to learn such effective coding techniques.
