Outside of "the bubble" the web is basically made of php and perl. Its like the dark matter of the internet. If you want to reach all they way down to the weekend dabbler, you really need to choose one of those 2, and of those 2, php seems more immediately accessible.

Sadly the web is made up of a lot of php code. Luckily this graph lets me sleep better at night:

I think you'll find that graphs like that are meaningless. I work for an agency that does mostly PHP work, and we never advertise, because for common skills like PHP, recruiters and potential hires inundate us with calls every single day. I expect the very common skills like PHP are severely under-represented in ads for this reason. For less common skills, you need to advertise, as people won't know where to go.
