What is CodeIgniter?
CodeIgniter is a PHP MVC framework for developing applications rapidly. CodeIgniter provides out of the box libraries for connecting to the database and performing various operations. Like sending emails, uploading files, managing sessions, etc.
Advantages of CodeIgniter framework.
CodeIgniter is a powerful PHP framework with a very small footprint, built for PHP coders who need a simple and elegant toolkit to create full-featured web applications. If you’re a developer who lives in the real world of shared hosting accounts and clients with deadlines, and if you’re tired of ponderously large and thoroughly undocumented frameworks, then Codeigniter might be a good fit.
CodeIgniter is an Application Development Framework – a toolkit – for people who build web sites using PHP. Its goal is to enable you to develop projects much faster than you could if you were writing code from scratch, by providing a rich set of libraries for commonly needed tasks, as well as a simple interface and logical structure to access these libraries. CodeIgniter lets you creatively focus on your project by minimizing the amount of code needed for a given task.
It kind of resembles the Struts framework
Codelgniter Development is one of the best PHP frameworks in Web Application Development. If you are looking forward to developing the application in a better way, then the only option is the web development framework. As compared to the other frameworks, CodeIgniter Development is fast, reliable, its time and speed are significant. You can modify (software) for use on a different machine or platform for existing codes by using the PHP framework. PHP server-side scripting language is very useful, In PHP software development, PHP programming or PHP application development or outsourcing PHP it is used.
Professional CodeIgniter developer’s programs are the best part of PHP framework for web application development. So Codelgniter Development concluded when you need a framework, exceptional performance. You can prefer Cake PHP (web applications development) and Zend Framework (as a toolkit) for users who design websites using PHP. If you were writing the code, then it has a motive to enable to develop the projects which could be faster.

Security features:
-
Remote code execution: <?php if ( ! defined(‘BASEPATH’)) exit(‘No direct script access allowed’);?> This ensures that the PHP file is not accessible directly by manipulating or running a script, which would compromise the system.
- SQL injection: This type of attack is highly common on the web. A SQL injection occurs when an attacker exploits the front-end and the post data to retrieve secure data from the database. According to CodeIgniter manual, it becomes evident that your web application is automatically safe from SQL injection as the POST data is retrieved in the controller using $this->input->post (‘’); which is automatically filtered by CodeIgniter. CodeIgniter User Manual excerpt proves this fact: “Beyond simplicity, a major benefit to using the Active Record features is that it allows you to create database independent applications since the query syntax is generated by each database adapter. It also allows for safer queries, since the values escaped automatically by the system.”
- XSS Attacks: An XSS or Cross Site Scripting attack is unarguably the common reason for the demise of web applications. An XSS attack works by a hacker crafting a malicious URL into the browser in order to compromise the security of the application. CodeIgniter has a built-in XSS filter which initialized automatically. In order to double check the security threats against XSS attacks, a Firefox add-on called XXS I can use to test the sample application against 96 different types of attacks. The results are shown in the image below. It shows that all form input fields were not found uuencoded, which means the XSS filter within CodeIgniter did its job.
- Other features: Apart from the ones mentioned above, there are a few minor security features that web application developers can apply. For example, make sure your web application does not allow any two different user groups to access each other’s accounts on the same session. This is possible by having the session data encoded with user id and user type so it can use to determine if the account belongs to the user whose user data is in the active session.
When it comes to storing passwords, the MD5 algorithm should use to encrypt passwords. Also, if you are using file uploads, make sure the file names are encoded with a random 32-bit string so that private or sensitive information is anonymous. In addition, CodeIgniter’s form validation library can prove to be very useful. Form validation ensures that invalid information is not entering into the database. To provide a double layer of security, the SQL structure can be as such that it each field conforms to the incoming form data by a) type and b) length.
