Is there a PHP library for comparing two paragraphs and show differences of inserted or deleted?

Question

I am developing a lyrics importing website using PHP in CodeIgniter framework. In that website I need to compare the old lyrics and new lyrics after using editing.

I need to show what user deleted from previous and inserted.

Is there any algorithm or library?

Similar question has been answered here, although a little bit older question: Highlight the difference between two strings in PHP

There are as well countless other "diff" packages/libraries available. They do not need to be CI specific in order for you to use it.
