And that's not counting all of the messes that are inflicted on you as a user of PHP - security holes and password breaches or having to interface with some crappy API to get stuff done.
At least with PHP it's likely to be some vaguely HTTP/POST-ish interface, not some XML/WSDL monstrosity...
The money is nice, but after watching the ridiculous waste of PHP idiocy for the Nth time, you can't help but want to get people to stop.
