CodeIgniter Web Application Architecture

by ketan patel

CodeIgniter, with its many advantages for the web developing organizations and CodeIgniter developers, is becoming a popular PHP framework. If one looks at the architecture of any application built on the CodeIgniter framework, it mainly relates to the three modules in its directory. First being the application, then the system and at the end, user_guide.

Relating to the general flow of the application to be created, any request that comes for CodeIgniter always goes to index.php page as the first step in the collective development process. Next process is routing that either passes information to security or caching. Security is one of the main points of routing process for any CodeIgniter development company that keeps the information secured and maintains the application order as well. In case, the information is routed towards caching module, then the information being input from CodeIgniter passes once again to the user developing the application. When the information request is passed to security, having secured information, the request is passed to the application controller. Application controller is one of the main building blocks of the CodeIgniter framework that is connected to the modules such as libraries, plugins, the language script, helpers and the models with the two-way information path flow. For a CodeIgniter web development company, the application controller plays an important role due to the dependability of all the modules on the same. Once the information flows among the application controller, the request is passed on to the view. The view section renders all the data that is available to it and then passes the information straightaway for caching process. In case the page was unable to get cached before at the time routing of the information, it gets completed in the present part and therefore, caching is completed when passed on the information to the CodeIgniter developer.

With the above flow path, the whole application built with the CodeIgniter framework gets completed with the significance of the MVC architecture. One can observe that all the three modules of the architecture are covered by the above mentioned workflow of the information being input, then passed on through the entire structure of the MVC system and then, again passed on the CodeIgniter developer developing the application.

Relating to the directory architecture of the CodeIgniter application, the three modules, as mentioned above are application, system and user_guide. Thus, it is divided into three parts.

In terms of CodeIgniter development, application plays a significant role containing all the code that is created while building the application with the framework. The application folder also contains other several folders such as cache, configuration, controllers, core, helpers, hooks, libraries, models, third_party and views. Thus, one can say that all the MVC architecture of the CodeIgniter framework is incorporated into the applications folder.
System is another main folder in the CodeIgniter directory and consists of libraries, helpers, databases, fonts, language core, and etc. The core consists of the core class of codes that are not to be modified by the CodeIgniter developer. If there is any kind of development that takes place, it is the application folder mentioned above. Libraries consists of the all the standard CodeIgniter libraries. One can create own libraries and also, can replace the standard libraries.

Lastly, the user guide of CodeIgniter framework is basically the offline version of the CodeIgniter guides all the architecture information and the files for the purpose of building the CodeIgniter application. With regards to the index.php, developer of the CodeIgniter web development company utilizes the liberty to create the error level by the developer, the environment of the application and define the application folder name as per the convenience.
Thus with all the points mentioned about the information workflow of the application and the directory structure of the CodeIgniter framework, it is a recommended practice for a CodeIgniter web development company to use the libraries and not to edit them in case there are experienced CodeIgniter developers.

CodeIgniter Web Framework: The Dynamic Websites Builder

by ketan patel

When it comes to a framework that meets all the server side requirements in terms of scripting language, PHP is regarded as one of the most powerful general purpose programming language. CodeIgniter being an open-source software for the purpose of developing the web applications rapidly, the framework has gained popularity among the back-end developers. At present, the CodeIgniter web framework can be listed as one of the top favorites among developers for many reasons and the competitive advantages of the framework.

The development of small websites can be simply accounted with PHP framework abilities having no limitations. The developer can simply extend all the HTML files including dynamic content present in the database and further easily able to process forms. Thus, there is no need to worry unless the size of the site is small. But, when it comes to creating and developing huge websites with PHP framework, analyzing the coding structure, one can easily get the logic of repeating codes in several pages. Developers can easily change the coding amid the pages, but notably it may get little complicated at the time of restructuring the code as it might affect some of all the pages irrespective of the amends done in pages.

Counting another major limitations to the earlier PHP platforms, whenever working in an ongoing project if any new developer is introduced, it may become tedious job for the developer to cope up with the existing code structure by reviewing and analyzing it and definitely responsible for lower productivity. Simply put, it might take long time for getting familiarized with the code comparatively. Every developer having good coding skills and depending on number PHP projects done in the past, develop its own coding style and as it is a script be coded, might vary according to the development project as well.

When it comes to development with PHP in an organization, enterprise class applications with huge scripts are structured notably one HTML file per page with PHP code might not be optimal in performance. The reason to it is structuring of the code itself adding with collective efforts of the team working over the development part and therefore, there might be a lot of confusion in the developing the entire framework. Therefore, when it comes to many developers working in an organization on a single project, it might not be easy to manage a productive code in minimum time due to the stated reasons and therefore resulted into a CodeIgniter development company having more popularity at present.

Web applications frameworks attributes to providing the structure of the web application with the “separation of concern” of modules. This helps in segregation of the the coding structure and provide the better assistance to creating the overall coding therefore, the end code relates to a a better code. With the agile methodologies for the incorporating testing and analysis of the site, the shape of the code developed at the end of the project accounts to better productivity, which is one of the main reasons for development of the CodeIgniter framework. Since CodeIgniter introduced in the market, it has become popular in many organizations and therefore, resulted several into CodeIgniter Development Companies.

Next, as previously mentioned the agile methodologies, code is kept on reviewing with parallel to the development of the project, CodeIgniter framework works on the similar approach and consists MVC (Model-View-Controller), which keeps on checking the coding structure of the code during development. Model-View-Controller has become a popular software designing and development pattern. Where Model is the lowest level of the pattern and responsible for maintaining the data, View is responsible for displaying the data and Controller is code, which when run maintains and controls the interaction between Model and View.

CodeIgniter is known for the MVC design pattern having logic as well as separated in terms of concerns. The best part MVC structure is the Controller that handles all the HTTP requests incoming to it and passing all the data to View. Model is the attribute that encapsulates the entire business logic of the application and interacts with the database.
When it comes to CodeIgniter, the views can be any type of page, template or any other layout file that can be created. It is important for a CodeIgniter development company that the developers amend the Model based on the views and therefore, the exact structure of the coding to avoid any kind of confusion.

Notably, MVC approach in CodeIgniter is loos, which exactly means that in CodeIgniter framework, the model files are not necessarily required. This accounts to multiple reasons. The very first reason being the database library of CodeIgniter framework can be used in both, the Controller as well as Model. It means that the extra separation of Models could be easily bypassed by the developers that definitely saves time. The second advantages of the Model is that it does not have any limitation of remaining tied to just one frameworks, but it is also compatible to the other frameworks such as Ruby on Rails. Thus, the third benefit of the developing any application the advantage the CodeIgniter development company has, is that the if the Model files of in the framework causes any sort of complexity in the developed application, the Model file can be simply ignored. This accounts to CodeIgniter’s advantages in comparison to the other frameworks.

The other features of the CodeIgniter that any developer in a CodeIgniter development company can get advantages of, relates to the using the model file in terms of developing and designing even if the Model files are optional to the task or the collective development technique. CodeIgniter allows the the Model to be used in the several Controllers. Secondly, when the developer need to change the function of the developed code, then rather than editing all the controllers, it is just required to edit the Controller at single place. Additionally, all the complex queries while developing an application, should be grouped together in the Model, which leads to one of the best simplified application in terms of development. Thus, with regards to the recently developing technologies, a CodeIgniter development company has an advantage over its other generic equivalent companies in making the services and products competitive and simply achievable as a valid point of comparison.
