I was wondering that as well. While I was at it, I wondered why not use __to_str(), as per the PHP coding guidelines.
because that's *against* php coding guidelines :)
You should have a look at the guidelines for METHOD-naming, which is part of the OOP part. It states that for method names, the camelcaps convention is used (aka "studly caps")

The short answer: Because PHP isn't Java.
The long answer: Two underscores denote what PHP refers to as a "magic method". You shouldn't have your own functions with the same names (unless you require that magical functionality). Have a look in the PHP manual under the "Magic Methods" section for more info / examples.
