/**
|
|
* Slinky allows you to go back and forth between "long" and shortened URLs
|
|
* using popular URL shortening services.
|
|
*
|
|
* Slinky assumes you have cURL installed and working, and requires the JSON
|
|
* extension installed if you're working with a service that uses JSON.
|
|
*
|
|
* Slinky will ONLY work with PHP5+
|
|
*
|
|
* It supports some of the more popular services, with easy extensibility for
|
|
* adding your own relatively easily. It defaults to using TinyURL
|
|
* for shortening URLs. If you want to use some of the other services, you need
|
|
* to set some configuration options before actually shortening/lengthening
|
|
* URLs. I'd strongly suggest that you cache results using memcached, a local
|
|
* DB or whatever to avoid having to hit APIs etc every time you encounter a
|
|
* URL.
|
|
*
|
|
* Slinky supports shortening, and auto-detection (for lengthening URLs)
|
|
* using these services:
|
|
* - Bit.ly
|
|
* - Tr.im
|
|
* - TinyURL
|
|
* - Is.Gd
|
|
* - Fon.gs
|
|
* - Micurl.com
|
|
* - ur1.ca
|
|
* - Ptiturl
|
|
* - Tighturl
|
|
* - 2tu.us
|
|
* - Snipr / Snipurl / Snurl.com / Sn.im
|
|
*
|
|
*
|
|
* To use Slinky:
|
|
*
|
|
* $slinky = new Slinky( 'http://dentedreality.com.au/' );
|
|
* - Creates a new Slinky instance, will default to using TinyURL for ->short();
|
|
*
|
|
* $slinky = new Slinky( 'http://dentedreality.com.au', new Slinky_Bitly() );
|
|
* - Creates new Slinky, forces use of Bit.ly for ->short();
|
|
*
|
|
* $slinky = new Slinky( 'http://dentedreality.com.au/' );
|
|
* echo $slinky->short();
|
|
* - echos the short version of http://dentedreality.com.au/ (default to TinyURL)
|
|
*
|
|
* $slinky = new Slinky( 'http://tinyurl.com/jw5sh' );
|
|
* echo $slinky->long();
|
|
* - echos out the long version of http://tinyurl.com/jw5sh (which should be http://dentedreality.com.au/)
|
|
*
|
|
* $slinky = new Slinky( 'http://dentedreality.com.au/' );
|
|
* echo $slinky->long();
|
|
* - Attempts to lengthen the URL, but will not auto-detect which service it is
|
|
* so it will just output the original URL. Useful for always attempting to
|
|
* lengthen any URL you come across (fails gracefully)
|
|
*
|
|
* $slinky = new Slinky( 'http://dentedreality.com.au/' );
|
|
* $slinky->set_cascade( array( new Slinky_Trim(), new Slinky_IsGd(), new Slinky_TinyURL() ) );
|
|
* echo $slinky->short();
|
|
* - Uses the powerful cascade mode to make sure that we get a short URL from
|
|
* Tr.im, Is.Gd or TinyURL (in that order).
|
|
*
|
|
* See specific service class definitions below for examples of how to use them,
|
|
* as some services allow (or require) additional properties before you can use
|
|
* them (for authentication etc).
|
|
*
|
|
* To use a different service with Slinky, just create your own class and
|
|
* extend Slinky_Service(). Make sure you implement url_is_short(), url_is_long(),
|
|
* make_short() and make_long(). If you need to GET or POST a URL, you can use
|
|
* ->url_get() and ->url_post(), which your class will have inherited.

$slinky = new Slinky( $url );
