Learning one language at the time vs several simultaneously?

Question

What do you recommend? Focusing on one language only and then move on to others that complement it, or picking all the ones to achieve your goal at once and tackling them at the same time?

I want to create web apps for data handling. Should I go full blown html/css/php/mysql/python. ...or one step at the time?

Share your experience.

Thanks!

Answer 1

Learn them in this order. HTML, CSS, Javascript, PHP, SQL.

Answer 2

I think that you should learn the languages one at a time, so that you don't get confused.
