Well, first you may want to check out this thread.

Now, to understand the above - you must understand the define() function. My explanation was stupid, so it's replaced with this:

Yeah. Say it's called a constant, it's kind of like a variable in the sense that it stores data, however, once the data is set, it cannot be changed, the data can be only be scalar, and it is accessed differently.

So:

<?php
define("hello", "How are you today?");
echo ${hello};
?>

Would return:

How are you today?
