Give me a break, it's not like there are only PHP jobs out there. If you can't find anything else then it's because you're not capable of coding something that is outside PHP domain, IE basic CRUD apps ..
In many ways, if a "coder" comes in and starts wanting to change a bunch of things purely because they are opinionated about languages, then that person is not going to go very far.
PHP: 30%; .NET for finance/enterprise: 25%; Java for finance/enterprise: 20%; Java for android: 10%; iOS: 10% (~5% overlap); Everything else: 10%.
And as far as payscales go, PHP is nearly always > the "Everything else" unless it's super specialized. But clearly everyone paying median or above for PHP is getting conned and they should convert their entire business to [flavor of the month] language.
[edit]And I'm leaving js off there on purpose as there are very few web devs who are expected to only work in PHP and never touch the js. And in those other orgs, you usually have a specific "front end" developer that probably doesn't deal with any other kind of code and makes less than the "full stack" devs.
citation needed, I don't believe one second these figures are accurate.
