get_instance method in codeigniter

In this article, we will discuss the "get_instance" method in codeigniter.

Purpose

In codeigniter, $this is used to get an instance of the current class. The object $this works well if you are using the object in model, views or controller.

But you cannot use $this inside your custom classes. You can use the get_instance method instead of $this object.

Example

Let us consider an example in which you want to call helper class in custom class. You can use the following code.

$c = & get_instance();

$c->load->helper('date');
nice_date(NULL, NULL);

In the above code

      1. The first line gives the instance using the "get_instance" method.

      2. Second line loads the helper.

      3. Third line calls the method "nice_date".
