To answer your comment on the other answer:

Writing Hello Warren is static. It would be the same for everyone who visited the site. echo "Hello ".$user."!" will replace $user with whatever name you specified as your name when you created an account.

As an example, when you create an account on facebook and fill out your profile, your name, birthdate, etc. are all saved in a database. When you put something like $user in your code, your code references the database to find out what your name is so it can display your name instad of a static element like Warren for everyone.

In php language, the point is the concatenate string symbol, and the echo function, outputs the content.

p.eg:
I asumme the value of the variable $user is Warren
echo "Hello ".$user."!" outputs Hello Warren!

That's it! :)
