PHP is responsible for the commoditisation of developers. PHP salaries and contract rates are 20% less than for Ruby, Python and Node.js here in the UK. The demands of the job are just the same, ie. Laravel = Rails = Django, but companies assume they can get good developers 20% cheaper just because they use PHP. That's gotta be the main reason to stop using and promoting PHP.
Blaming the language for the market is a mistake... If you stop promoting PHP, more devs will start on other language, and the market will pay lower, since there is more people to pick from with that particular skill...
