To check the version of the CodeIgniter framework installed on your system, you can follow these steps:

1. Open a terminal or command prompt window.
2. Navigate to the root directory of your CodeIgniter project.
3. Look for a file named "index.php" in the root directory of your project. This file typically contains the version information of the CodeIgniter framework.
4. Open the "index.php" file in a text editor.
5. Look for a line of code that defines the CI_VERSION constant. This constant holds the version number of the CodeIgniter framework.
6. The version number will be in the format X.X.X (for example, 3.1.11).

Alternatively, you can also check the version of the CodeIgniter framework by running the following command in the terminal or command prompt window:

1

php index.php --version

This command will display the version number of the CodeIgniter framework installed in your project.
