Codeigniter Tutorial for Beginners


What is CodeIgniter?

You spend a lot of time writing the same code over and again when developing a web application. Frameworks provide you a place to start and reduce the amount of code you'll need to create a website.

CodeIgniter is a PHP-based framework, however it is not a PHP replacement. You don't have to abandon PHP just because you're learning CodeIgniter. PHP is a server-side scripting language that may be used to create dynamic web applications.

CodeIgniter includes libraries, a clear interface, and a logical structure for accessing these libraries, as well as plug-ins, helpers, and other resources that make it easier to solve difficult PHP functions while retaining high performance. It shortens the time it takes to create a fully interactive, dynamic website by simplifying the PHP code. It requires PHP 5.2.6 or higher, as well as MySQL 4.1 or higher.

Why you should use CodeIgniter

If you're looking for a framework with a minimal footprint, look no further.
  • A high level of performance is required.
  • I'm looking for a framework that doesn't require any setting.
  • I'm looking for a framework that doesn't rely on the command line.
  • I'm looking for a framework that doesn't need me to follow stringent code guidelines.
  • To achieve a more streamlined code structure.

Features of CodeIgniter

Because of its many features and benefits, the CodeIgniter framework is in high demand among PHP developers. A web application built with CodeIgniter operates well and quickly. It offers a comprehensive set of features for creating a dynamic web application from the ground up.

Important Features

  • It is completely free to use
It is free to use because it is licenced under the MIT licence.

  • The MVC pattern is followed.
Model-View-Controller is used, which separates the logic and presentation elements. The controller receives the request, the model performs the database activity, and the views present the output.

However, with standard PHP scripting, each page represents MVC, which adds to the complexity.

  • It's light.
It is very light in weight. The CodeIgniter core system only requires a tiny library; however, more libraries may be added dynamically in response to your demands. As a result, it is quick and light in weight.

  • Create URLs that are optimised for search engines.
CodeIgniter generates clean and search engine friendly URLs. Instead of using a query-based technique, it uses a segment-based approach.

  • Libraries built-in
It includes comprehensive packet libraries that enable all web-related functions such as database access, form validation, email transmission, image manipulation, and email transmission.

Some other Features

  • Security and XSS Filtering
  • File uploading, session management, pagination, data encryption
  • Flexible URI Routing
  • Zip encoding class
  • Error logging
  • Full page caching
  • Localization
This Codeigniter tutorial is beneficial for both experienced developers and beginners who want to learn how to build websites with creativity and ease using the Codeigniter framework.
