I've no idea and I suspect that everyone will have a different opinion. What are you wanting to code? Or are you just trying to make yourself employable? Personally I'd recommend PHP if you are wanting to create websites but it would be hopeless if you wanted to write a computer program. Foxpro was really, really easy to learn but it wasn't OO so it was eventually made obsolete and who wants to learn an obsolete language?
If you want to create websites then I would suggest you to learn HTML, CSS, Javascript, PHP If you want to create console program then try your hands on C
The question is about as useful as "which car should I buy". Without any qualifying criteria, you'll get different answers depending on the preferences of the person answering. As sarahk asked, what is it you wanna code?
