I want to send SMS messages to multiple numbers in my database based on an event happening. I was wondering if there is a way of doing this in PHP or Javascript? Maybe there is a function like php's mail function?

If not does anyone know of any good and easy to implement systems paid or free?

I'd like to have a go at developing something like this myself, but have a feeling that it might take me a long time.

Any other information or tips on the subject would be greatly appreciated.

Thanks for the time.

Oh, also I'm using Ubuntu server if that helps.
