Hi room, is comment really necessary while writing code?? Most especially in php

Answer 1

Totally necessary! You will beg for the comments first time you start working on other people code, but who knows maybe you will be lucky not to do it :)

Answer 2

You should comment your code so when sharing it with other people they won't lose much time trying to understand it.

Answer 3

And also it will help you to understand what actually you're going to do in your code.
