//loading the template view file $this->template->set_view('welcome_message.php');In this example, we have used the set_view function to load the view file "welcome_message.php" into our framework. The $this->template is an example of a package library that contains most commonly used templating functions. In the above example, by using the set_view function, we were able to direct the application to load that particular view file. The set_view function can be used to load any view of our choice in the framework, and it is often recommended to take extra security precautions when handling user input, to avoid unauthorized access to sensitive files or data stores. The set_view function is just one example of the many templating functions that are part of modern PHP libraries and frameworks, allowing developers to build more modular, maintainable, and efficient web applications.
