Call Model method from another Model in Codeigniter

In CodeIgniter, the Model is used for the Database manipulation – fetch, insert, update, and delete records.
If within the project there are multiple Models are available then it may require to perform the action during a Model which is already created in another Model.
In this case, you’ll either create a separate function to perform an equivalent action or use the already available method within the Model.
It is possible to reuse the method in the Model from another Model.
Models are loaded within the Model as same as loaded within the Controller using $this->load->model().
Create Three Models and call 1st and 2nd Model methods from the 3rd Model.
