Frequently in PHP I found myself missing a proper REPL, yes PHP can be run interactively with `$ php -a`, but it doesn't print the last returned value, so spelunking in a running system is slow and awkward, luckily I've found Boris(https://github.com/borisrepl/boris) which is more like IRB or Pry, but it's still unpleasant when I'm trying to kill a tricky bug. On the package management front Composer is a better solution than previous PHP offerings, but it's got some quirks that make it seem unpolished compared to Bundler.
If I was given a choice PHP I would never willingly pick PHP. I suspect your company is pressuring you to move because they think they can get PHP devs at a lower cost than Ruby devs. If you're in the Bay Area there are plenty of companies that will hire you to write Ruby so you don't really have to switch if you're not comfortable with it.
