Okay, cool. I'd go to events, meet people in organizations using php/JS stack (or other tech stacks you know), ask them to grab lunch. Your story could go something like this:

"I'm a self-taught programmer looking for my first full-time programming job. If I describe my experience, would you be able to describe the skillsets I need to develop in order to be successful in your organization?"

I did this repeatedly and got tons of useful feedback. See my customer development essay in earlier link.
