On php it can be easy and fast too

In my opinion, the php language has always been a pretty good solution for creating a complex backend of web applications, and in the nineties and zero it gained such immense popularity (just huge, comparable to IE for web surfing at that time) primarily due to the ease, speed of development and code support. But those days are over. Today it is believed that php applications have become monstrous, take a long time and are difficult to run, can only work with pulling a lot of dependencies into the / vendor directory ...
