CodeIgniter 4 allows creating helper files to store collection of reusable functions. Require loading the helper before using that helper file function.
Helper functions offer numerous advantages. They encapsulate repetitive or complex code into reusable functions, promoting code reusability and maintainability. By abstracting common functionality into helper functions, developers can write cleaner and more concise code, enhancing the overall efficiency of their development workflow.
Files are stored in app/Helpers/ folder.
In this tutorial, I show how you can create helper functions and use them in the controller and view in CodeIgniter 4.
