Hey guys, I'm fairly new to programming general, but I'm now fairly confident with my C# and Xamarin and XML skills. I'm looking to move up to learn server side programming for apps in particular, to be able to build apps that can connect to a traffic of users.
Can somebody please guide me what I should learn? There seem to be too many things out there.
1) PHP and XAMPP for testing, and then Tomcat for deployment?
I've heard of all these technologies, but the only ones I have a fair idea about are PHP and XAMPP because I've learnt some website building in the past. What should I learn, in today's technology landscape?
