is PHP acceptable? well, obviously it depends on the project requirements, for instance programming a chat server in PHP is probably not the best choice, but even though PHP has its faults for me it remains a solid language for building new web applications. Here's why: 1. Its easy to scale (horizontaly) because it has a "share nothing" archtecture. 2. like tjlyte states its centered on the HTTP protocol which is almost always your app protocol 3. its fast 4. its an "easy" language to program, but still supports OOP, namespaces, closures, anonymous funcs, etc. 5. Its highly portable 6. It has a very extensive developer base, tons of libraries and frameworks that are starting to reach enterprise Java level maturity (Flow3, Symfony2 for example )
