Well, if you've ever wanted to take your PHP knowledge and apply it to the .Net framework as bytecode, your ship might have just come in. Over on the PHP# Project Page there's a programmer working to create: a PHP compiler for the CIL (.net bytecode). - So far the useful bits are, a modified Jay generator that creates PHP code, a modified C# lexer and the mono mcs tokenizer class using the C# lexer.

The site gives all sorts of information about this project, including why he's doing it, how he's going about it, and why he's using PHP to try to create all of this. It's an interesting idea, but honestly, I don't know enough about it to see it's usefulness. I can see working things in with .Net and Mono being a good thing, but this statement scares me a little: PHP# indicates that the eventual language may not be that close to what you are used to today as PHP, but more a derived language - which will probably have to include a number of features advantageous for the .Net bytecodes. So, basically, it would be PHP, but it wouldn't?

Thanks to Ewald for the link...
