My company was looking for a Scala dev in the UK desperately. Yes, perhaps there are not too many Scala jobs out there as there are Java, .NET and PHP, but good Scala developers are not easy to find either. So adding a bit to your list of which language to add to your resume, I would go and spend more time on Scala than on PHP personally.

Why Scala? well, if you came from Ruby, I bet 9/10 you'll like it more than Java, and I bet 10/10 you'll like it more than PHP.

More and more enterprise software companies adopt it (citation needed, but I know my company does). at least it has more chance in being adopted in the enterprise than Ruby

Also it is not completely uncool for startups, you can find your handful of Scala based startups, and I think there is a trend of more and more using it (as it's not as bad as Java in terms of fun, and much better than Ruby / Python in terms of performance)

Sorry I can't offer you a job at the moment, but as a middle ground between cool startup technologies and boring corporate Java EE / Spring etc... I think Scala might be a niche that will get you that job you want (perhaps not the one you need to get immediately)
