We use PHP as our main backend preprocessor. Being a well established language, it is supported by a large community as well as a dedicated team of developers. It is used for much heavier projects that do not require realtime processes as well as being used in a hybrid system alongside NodeJS.

PHP has been the backbone of what we've done at Visualsoft for years. We have lots of experienced people who have used it and know how to get the best out of it. It's come on leaps and bounds over recent years, and is the basis of pretty much everything we'll build with.
