Attila Szabo has come up with a class that makes sending SMS messages from your site simple (through the smsBug gateway).

I wrote a simple PHP class for sending SMS messages through smsBug gateway. It can send a single SMS message and receive the number of credits left (see the UML diagram of the classes below). You need to include two classes into your PHP code.

He includes an example of it in use (sending a single SMS message to a phone) as well as a demo of it in action and a link to the download where you can grab the class for yourself.

Cell phones have become ubiquitous in our society, making it possible to get information instantly through things like SMS messaging. If you've ever looked at your phone and wondered how you could send the same kinds of things from your scripts, this post on the Zend Developer Zone is a push in the right direction.

SMS messages have become ubiquitous in most of the world. As with any commodity technology, those who make their money off of it are always looking to expand it so that they can charge more. In the SMS world, there is the MMS, Multimedia Messaging Service. Developed by the Open Mobil Alliance MMS is designed to deliver rich content messages over packet data services.

That's all well and good but without the proper tools how are you going to message (spam) the cell-phones of your closest 25,000 friends with the latest release (obeying all relevant copyright laws, of course) from your favorite band? Well fear not, Stefan Hellkvist over at hellkvist.org has rushed to your rescue. The library, MMSlib, is used to encode and decode MMS messages in PHP.

There's no tutorial here, just information about the library and more pointers to the site. The MMSLib code is released under the GPL.
