CodeIgniter 4 – Build a complete web application from scratch

CodeIgniter

CodeIgniter 4 is a new, fast, lightweight PHP MVC frame, which helps people to quickly and easily create stable applications. It is easy to install and to use; shared hosting works well. CodeIgniter offers a range of standard work libraries that can be concentrated on the project by reducing the amount of code that must be written.

An Introduction to CodeIgniter

  • People can use a lot of pre-written features in CodeIgniter in your program. Domain access, URL manipulation, sessions, authentication, cookies, and much more are all open to them. This will save them a lot of time.
  • CodeIgniter provides a framework for growth. Data of a certain kind, for example, are stored in specific locations. There are also some naming conventions that must be followed. Getting any of these choices taken for you helps you to rely on what matters most: the functionality of the submission.
  • If a person is new to PHP, CodeIgniter offers an extra benefit: by imposing a framework and offering a wealth of prewritten features, they will need a much narrower knowledge base to be useful.

Concepts of CodeIgniter

It is essential to study some of the definitions used by CodeIgniter before operating with CodeIgniter. The MVC model operates with CodeIgniter. MVC is the model, display, controller. Models provide classes of data handling code, HTML/Javascript views, etc. that are part of the application’s visual part, and controls are the traffic cops that integrate both.

CodeIgniter also understands many other categories of files beyond templates, views, and controllers: aides and collections. Function libraries are helpers. They can either be app-specific or general and can be used once again. Libraries are groups to improve the program. CodeIgniter has more than five file forms. However, the files for which you are using 98% reflect templates, views, controllers, helpers, and libraries.

How to design PHP applications using CodeIgniter.

  • Installing and setting up the code easily
  • Find out how to distinguish the application code from the presentation code
  • CRUD operations (creation, reading, updating, deletion)
  • Login: Login to the user account
  • Authentication: Mind me the password
  • Account management with users administrator
  • Email Activation of Account
  • Password reset user-initiated
  • Uploading and editing of images
  • Ajax and JSON applications
  • CSS Framework styling
  • Internationalization: content displayed in multiple languages
  • Usage: downloading the shared hosting program

Important skills needed to rapidly design apps for CodeIgniter

Using a plugin speeds up the development of PHP web applications. There are many implementations to pick from, but some need a lot of setups and need a strong server to run. CodeIgniter is a small but efficient platform that’s simple to set up and runs on shared hosting. This course will take you from the ground up, from downloading the code to creating a full web application and finally deploying it to a live server.
