Key Reasons to Choose Codeigniter Framework for Your Next Project

PHP is one of the programming languages that has become one of the most powerful web development platforms in a short span of time. Its massive popularity can be seen from the fact that today it is installed on more than 2.1 million web servers worldwide and at least 378 million web applications are running on it.

Ever since PHP tightened its grip on the programming world, a plethora of frameworks—CakePHP, Laravel, Symfony, Codeigniter, and Yii—entered the market with their own set of tools and functionalities. The aim of all of them is clear: better and faster completion of small or large web development projects.

Among the many PHP frameworks, Codeigniter is widely used. Let’s get into details about what makes Codeigniter loved by both businesses and developers.

What is Codeigniter Framework?

“… I have spent a couple of weeks researching and installing PHP frameworks, really banging on quite a few of them, and I was absolutely dismayed…”

The sour experience of Rick Ellis with different PHP frameworks is evident from the aforementioned statement. However, this experience motivated him to write his own PHP framework—which, today, we know by the name of Codeigniter framework.

Loosely based on the popular model–view–controller (MVC) development methodology, it is an open-source software rapid development web framework used to build dynamic websites.

The trending keywords on Codeigniter that we can see across search engines today, give us a mixed impression about this PHP framework. However, the reality is pretty simple and one-sided: Codeigniter is a robust framework and has been evolving consistently to meet the emerging web development trends.

Why Everyone Loves Codeigniter Framework

Rasmus Lerdorf, the creator of PHP, mentions that he likes Codeigniter because it is faster, lighter, and the least like a framework. The websites of many big organizations like Nissan, Buffer, and Casio are using Codeigniter PHP framework.

Let us learn the top reasons to choose the Codeigniter framework for web application development project.

  • Smaller Footprint

The official website of Codeigniter boasts of itself by quoting:

“CodeIgniter Rocks. CodeIgniter is a powerful PHP framework with a very small footprint…”

It is a lightweight PHP framework. Contrary to other PHP frameworks, Codeigniter has a very small footprint. It is only an incredible 2MB download, including the user guide! Despite its small size, Codeigniter is fully self-contained and does not rely on any other frameworks. Its small footprint helps make it faster, more than most of its competitors. thereby greatly eliminating the need to optimize the framework-based performance of the website.

A recent study on the ‘Memory Usage’ for Laravel and Codeigniter framework, published in The International Journal of Current Trends in Engineering & Research (IJCTER) clearly mentions that Codeigniter performs better than Laravel in terms of ‘Memory Usage’. A key excerpt from the study is as below:

Two functionally equivalent blogging web applications were developed and subjected to an experiment to evaluate and measure ‘Memory Usage’ of CRUD-functionality for both of the frameworks. The following results make Codeigniter an undisputed winner in terms of ‘Memory Usage.’

  • Save Time with Less Code

It does not take long to learn Codeigniter. Moreover, it quickly pays for your effort in the time saved later on.

With Codeigniter as a PHP framework, you type less and thus make fewer mistakes, which in turn leads to spending less time debugging your code. And it is a well-known fact that the smaller the code, the faster it loads, thereby occupying less space.

An Example of Writing a Database Query

The function within the PHP program to query a MySQL database is as follows:

mysql_connect("localhost", "fred", "12345

$result = mysql_query (“SELECT *
FROM sites”, $connection);
while ($row =
mysql_fetech_array ($result,
foreach ($row as $attribute)
print “{$attribute [1]}”;

The function to handle a similar query with Codeigniter framework is as follows:

$this->load->database ('websites');
$query = $this->db->get('sites');
foreach ($query->result () as $row)
print $row->url

Compare the character counts in both the cases and you will find 244 characters for the first case and 112 for the Codeigniter framework. Therefore, building a website with Codeigniter framework leads to less code, thus fewer errors.

  • Security

The user guide of the Codeigniter framework states:

“Codeigniter is fairly restrictive regarding which characters it allows in your URI strings in order to help minimize the possibility that malicious data can be passed to your application.”

If a secured website is the primary factor that your business demands; then undoubtedly, Codeigniter is a great choice. It makes it easier for programmers to write secure PHP applications by providing a number of features. Codeigniter framework can easily tackle threats like SQL injection, cross-site scripting attacks, and remote code execution.Codeigniter framework architecture

Moreover, its cookie encryption and decryption feature enhance the product development process. Apart from these features, you can further improve the security of the website by installing a number of plug-ins.

Whether you are planning to build a high-end website or the right platform for an eCommerce development setup, Codeigniter is the framework you can rely upon for sure.
