Describe when and why you should use PHP (as a server-side programming language). Why a client-side programming language (like JavaScript), not enough?

Also, is it generally safe to keep credentials like the Database passwords in PHP source code? Why? Compare that to doing the same thing in JavaScript.

Answer 1

Where and why use php?

Php is server side script so it is not executed on Client side, it execute on on server and generate output in html/js/CSS format and then it is visible to user.

So password or username and other sensitive information are must be use in php so it is safe and any hacker or user not able to manipulate data.

Why not JavaScript?

JavaScript executed on Client side. So all code written in JavaScript are visible to user and any hacker so then they can manipulate data and gain unauthorized access to website.
