Summary of the Article – CodeIgniter Hooks and Controllers
CodeIgniter’s Hooks feature allows developers to modify the inner workings of the framework without modifying the core files. It follows a specific execution process called the Application Flow.
The default controller in CodeIgniter is the file mentioned in the default controller setting. By default, it is set as “Welcome.php”, which is the first page seen after installing CodeIgniter.
CodeIgniter is built on the Model-View-Controller (MVC) development pattern. MVC separates application logic from presentation, allowing minimal scripting in web pages.
In CodeIgniter, classes are used as part of the Repository pattern and are optional to use with the Model.
There are two hook files in CodeIgniter- “hooks.php” in the “application/config” folder and the “hooks” folder in the “application” folder. Hooks allow running code repeatedly after the controller function is loaded.
The main difference between Helper and Library in CodeIgniter is that Helper is a file with functions in a particular category, while Library is a class with functions that can be instantiated.
In CodeIgniter, an API controller serves any client or device, while a normal controller serves only its client.
CodeIgniter is not considered a full-stack framework, but rather a tool in the Frameworks (Full Stack) category.
CodeIgniter supports four types of relationships: HasOne, HasMany, BelongsTo, and BelongsToMany. These relationships can be set up in models similar to Laravel.
In CodeIgniter, modules are used for code modularization, allowing developers to create reusable and separate units of functionality.
