Programming with CodeIgniter MVC
This chapter covers the CI libraries topic, and the different types of libraries and their different usage categories, with several code examples of web applications. The CI development platform provides us with the built-in libraries, enables us with an easy procedure to integrate third-party libraries, and also allows us to develop our new libraries and share them with the community, if we wish to.
The CI libraries are powering efficiency, code reusability, separation, and simplicity. The benefits achieved are as follows:
Efficiency: In means of minimal loaded resources. This feature achieved by the fact that the CI library, may be loaded only by the specific CI project controller(s), or even only in specific method(s), where the library's services are required. Hence, the overhead (memory) of the library resources during execution time is minimized in each controller operation state.
Reusability: Reusability means writing once a function code and reusing it across the...
