Find URLs In a Text and Shorten Them

/ Published in: PHP

This script parses the entered text and it gets all URLs from the text. It will then shorten those URLs and replace the long URLs with shortened ones in the text.
If you need only the Shortener Services script, take a look at this snippet <a href="http://snipplr.com/view/44115/shortener-services/">http://snipplr.com/view/44115/shortener-services/</a>
