i believe that every language has its perks, and PHP has quite a few. as far as back-ends go, there are a few types -xml/json webservices -low memory application servers(blogs, shopping sites, etc..) -high memory application servers(data mining, indexing, processing, game servers) i think php is a great low memory solution, when you get into higher memory loads for the app to process, you do not want to reload everything back in to ram for each request. php is single threaded per request, and as such you don't have access to sockets, or other event based activities on the server side. i agree with the statement in general, that you should go with what you know to be the most efficient language for the task.
