Before commencing with the best practices to increase PHP code readability, let’s get a brief introduction of Code Refactoring below:-
So, What do we mean by PHP Code refactoring?
PHP Code Refactoring is an act or a process of making the overall code of your website readable. In this approach, we tend to take the messy code and reorganize the same into easily manageable chunks.
Why is it important to consider code refactoring?
One benefit linked with refactoring is enhanced readability of website code. In addition, it allows you to achieve the following:
– Improved non-functional software attributes,
– Reduced code complexity,
– Easy-to-maintain source code,
– Improved extensibility.
Therefore, try to choose a custom PHP development services provider who can provide you a well-organized code repository. It also allows you to follow agile methodologies to serve the future scaling needs of your website.
Let’s see some common best practices that can help you to perform PHP Code refactoring during the development process.
- Don’t Repeat Your PHP code
In the programming world, the most popular coding principle is DRY (don’t repeat yourself). As this repetition of PHP code will lead to code duplicacy, that is not at all a good coding practice.
If you are duplicating the same code multiple times, you need to encapsulate the functionality in its own function and use same function to confront the repetition.
This will make sure that you don’t face any kind of inevitable bug fixes months down the line.
- Split up the Complex Functions
It is always of utmost importance that the code written by you is easy to understand. And, writing and using complex functions will lead to hard-to-read or understand PHP code.
So, it is always advisable to break down the complex functions into smaller and more readable and testable chunks. Try splitting up the large and complex bits of your PHP code. It will help you to see an amazing difference.
- Nested Conditionals’ Replacement
Another way to perform PHP code refactoring is to replace nested conditionals with guard clauses. This approach will simply help you to extract all conditionals that are calling an immediate return of a method’s value to put the same at the method’s beginning.
This approach also works well with the complex functions.
- IDE (Integrated Development Environment) Approach
IDEs or integrated development environments are actually useful while coding PHP web applications. (You can also consider PHP manuals) Adopting this approach helps you to write, edit, execute and debug the code through a friendly interface.
Its smooth syntax highlighting, navigation & documentation will also make sure that you write error-free and legible code. Using IDE model can eventually improve the readability of your code.
- Simplify Conditionals and Loops
Besides PHP built-in functions, you can also create your own functions (block of statements to repeat in a specific program).
Simplifying conditionals and loops while using functional methods is the most advanced type of refactoring PHP code. Some functions like ‘reduce’ and ‘map’ turns out to be beneficial to improve the overall readability of your code.
To Wrap Up
PHP Code Refactoring only tends to enhance the readability of your code written and that too without affecting its external behavior.
Basically, the sole aim behind code refactoring is to end up with a well-structured code that is actually helpful in your long-term website customization goals.
