PHP extract() function

We get to know about new functions when we go through the documentation or its use. When I was working with CodeIgniter framework in PHP, i noticed the passing of variables from controller to views to something like:

$data['username'] = 'abc';

$data['current_page'] = 'hello.html';

These variables when passed to the views, they can be accessed as:

echo $username;

echo $current_page;

It was all the use of php extract function that has this functionality.

So, for simplicity in accessing variables, this would be more useful.
