Computer Hope

Hi there,
I have basic knowledge of CSS, HTML, and JS  and I am planning on studying more in order to master programming. In my town, we don't have many academies for programming but at this moment I have the opportunity to choose between C# with .Net and PHP. What would be the wise choice to learn in 2019/2020?

Short and quick answer:
Get the Microsoft .NET thing. It is widely used and supported.   
I will leave to to others to tell you about PHP.
