"So before you jump on that bandwagon thinking nothing interesting could possibly be done with PHP"
The problem is not that nothing interesting can be done in PHP. Lots of interesting can be done in any Turing complete language. It would be just 'plus points' if you would use for example Scala for the kind of task you described. I just cannot see why to use a dynamic language in a task where performance is important when there is a statically typed fast language which is as good and as concise as Scala. It is not that it is impossible that I would join a company developing in PHP. We have to make compromises all the time. It is just that developers evaluate companies, and join the one with the most 'plus points'.
