PHP Quine

A quine is a piece of code that produces itself. It takes not input, and outputs a text that is its own code. The code is run to produce itself.

One may consider a file without PHP tags as a Quine: PHP executes such code by outputting the raw text. It is considered valid, yet too easy to be a quine.
