To use a framework or not to use a framework?

I am new to PHP and am trying to learn to code "by hand". I see all the "cool kids" are using Laravel and Codeigniter etc. and I know even less about those than I do PHP.

I just wanted to know if I should continue to learn php from scratch like I am now or learn how to use a framework instead? I am thinking long term now for when I one day want to try get a job as a web developer. I don't want to go to an interview and they say no right away because I can't use a framework.
