Break Up Code into Logical Parts
Lab: PHP 101: Gentle Introduction to WordPress Programming
Video Runtime: 07:55
We break up our code into logical parts in order to organize our code. In PHP we do this by files, folders, and functions. It lets us organize and structure our code. Why?
Imagine all of the code in WordPress in one huge file. It would have tens of thousands of lines of code. Imagine trying to work on that one huge file. It would be very difficult and prone to errors. It’s also hard to build code in teams.
We break up code to improve:
- readability
- reusability
- maintainability
Imagine that 3 months from now your customer calls you with a problem. If all of the code were listed in a file with 100,000 lines of code and no functions to break it up, imagine how long it would take you to find the problem and resolve it. Yuck!
Breaking up reduces our costs and the time to build and maintain code. Let’s talk about it.
Break. Go rest your noodle for a couple of minutes.
