Time Based PHP Greetings

Before we can greet the user based upon the time of day, we first need to find out what time of day it is.

<?php

$b = time();

$hour = date("g",$b);
$m = date ("A", $b);

First we get the timestamp for the current date using the time () function. For the purpose of our script the only important parts are the hour and the AM/PM. We set a variable for each of these aspects of the time.
