CodeIgniter is an open-source, web-based framework for rapid application development that helps build dynamic PHP web sites.
CodeIgniter is based on model-view-controller (MVC) work architecture but is very flexible and permissive concerning organizing the code.
CodeIgniter, on the other hand, focuses on simplicity, both in installation and in development and maintenance.
CodeIgniter can be used for any type of project, from blog or site to portal, REST Server or e-commerce store.
Compared with the other frameworks currently used, CodeIgniter stands out extraordinarily well in terms of ease of use.
Thus, it is in the top 5, both in popularity and memory consumption or speed.
Here are some of the reasons why it is worth trying CodeIgniter:
1.Easy installation (running on any type of hosting).
2. Minimum PHP Version 5.4.
3. Very little memory consumed.
4. It’s free.
5. Very fast.
6. Model-View-Controller Structure.
7. Continuous development and support for Bugs / Features on Github.
8. Full documentation.
CodeIgniter comes packaged with its own bookstores in almost every project, including Benchmark, Email, Caching, Encrypt, File Upload, Form Validation, Image Manipulation, etc.
As you can see, it is possible to load strictly what we need for a particular Route without additional classes and objects. This is why CodeIgniter has a very low memory consumption and is very fast.
You can also use Composer together with any bookstore if you want a faster project development.
As stated above, one of the strengths of the framework is the documentation. The CI document is ten times larger and more comprehensive than any other framework, and this is also possible due to the fact that CodeIgniter is supported by a company, not just a programmers community. EllisLab, the company behind CI, has plans to develop the framework, so they have no problem investing time in building quality documentation.
CodeIgniter allows you to add as many or few security systems as you want for your application. It does some things to automatically disable global variables (register_globals) irrespective of PHP directives or stop magic_quotes_runtime directives during system initialization so you do not have to remove slash when recovering data from the database. Other features like cookie encryption or SQL automated queries can be enabled.
Calendar, email, zip compression, validation, upload, unit testing, these are just some of the libraries that CodeIgniter contains. It also includes plenty of other helpful features such as forms, file handling, arrays, strings, cookies, directories, and much more.
It does not require PEAR packages or server changes to work. It is enough to upload the files to the server and you can get started.
Today, any decent framework includes database abstraction modules and CI is no exception. You can easily create, insert, update, or delete data from the database without having to write rough SQL commands.
