Understanding Security As A Programmer

Question

I am fairly new in my career as a programmer, but I have always felt my biggest responsibility has been providing clear, accessible and secure content to end-users.

That said, knowing next to nothing about security, how do I know and trust that I am handling security well? Where do I even start? I use primarily HTML, CSS, PHP, JQuery and Bootstrap. In the long run, I would like to build websites that securely handle purchasing from scratch.
