    Programming statements or comments?? Programming statements are required. In fact, you can't program without them!! Not clear on what you're talking about here.

      If you have ANY underlining logic in your website, you will probably need to use statements. Besides, PHP is very powerful programming language, and statements are literally one of the first concepts tutorials cover. The understanding of basic programming language concepts will always come in handy.

    Taher the best way to describe it is to think of a programming language as a brain with strict rules. I can't explain these in details here but they apply to most programming languages. (try W3Schools Online Web Tutorials for more information)

    One of those rules uses conditional statements which means if this then do that or this.

    So if someone asks you "Do you have to go to work today?" then your brain does this very instantly, almost even without you noticing:
    - Bring back today.
    - Today is Sunday
    - I don't work on Sunday
    - So you respond no I don't have work today.

    So in code it would be like:
    1) First find out if you know what today is (I know sounds crazy)
    today = Sunday

    2) Find out if I work on Sunday
    Monday = work
    Tuesday = work
    .....
    Sunday = off

    Response - I have today off. That's conditional.

    In programming you can use it for lots of reasons such as:
    - if the password is not correct then show "You've entered an incorrect password. Please try again".
    etc.....
