So I am wondering about that How Many Languages Have to Learn to Create a Website (which has - sign up or sign in form , data management , best encryption for client data ,attractive graphics, auto send e-mail and good sub-website and their data management )
Other than this all the information of visitors (cookies , visiting timing ,IP,clicks,etc )
Total I learned 3 language that are PHP,html5 and css .I think this 3 languages are enough.
So what's your opinion on this ?
Or other then this what I have to learn.
