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.

Please read the Introduction section of the User Guide to learn the broad concepts behind CodeIgniter, then read the Getting Started page.

CodeIgniter is installed in four steps:

  1. Unzip the package.
  2. Upload the CodeIgniter folders and files to your server. Normally the index.php file will be at your root.
  3. Open the application/config/config.php file with a text editor and set your base URL.
  4. If you intend to use a database, open the application/config/database.php file with a text editor and set your database settings.

If you wish to increase security by hiding the location of your CodeIgniter files you can rename the system folder to something more private. If you do rename it, you must open your main index.php file and set the $system_folder variable at the top of the page with the new name you've chosen.

That's it!

If you're new to CodeIgniter, please read the Getting Started section of the User Guide to begin learning how to build dynamic PHP applications. Enjoy!

System Requirements
  • PHP version 4.3.2 or newer
  • A Database. Supported databases are MySQL, MySQLi, MS SQL, Postgre, Oracle, SQLite, and ODBC

 I'm used to develop from Scratch and I hate using a framework since there is a lot of difference in syntax. But when someone suggested me to use this I started to like it and it did make my work more easier it seems like its already package. I recommend this
