In my opinion, at the time of this writing, both languages are nearly on an equal footing, although PHP is easier to deploy because there’s no per-compilation required. We will begin to see larger corporations adopting PHP only when Universities begin to include it as a major part of their curriculum, and as the smaller companies that hire graduates fluent in PHP grow into large corporations. In short, it could take many years before we really start to see a PHP presence in larger corporations.
