How does '$this->uri->uri_to_assoc(5);' work?

The 'uri_to_assoc' method is a part of the CodeIgniter URI class, which provides methods for working with the URI string. The 'uri_to_assoc' method takes a parameter that specifies the starting segment of the URI string from which to create the associative array.

Here is an example of how to use the method:

$url = '/blog/post/123';
$segments = $this->uri->uri_to_assoc(2);
print_r($segments);

This code will output:

(
    [post] => 123
)
