<?php
$emp = array("John Smith","Katie Holmes","Chuck Norris","Joe Blow","Ivana Humpalot","Katie Alvarez");
$empID = isset($_GET['empID'])? $_GET['empID'] : 0; // if empID is in URL get it, if not set it to zero
$previousID = $empID-1;
$nextID = $empID+1;
if($previousID < 0)
{
$previousID = count($emp)-1; // this will go to the end if you go back from the first one (loops), or you can set it zero so that it won't go past zero
}
if ($nextID >= count($emp))
{
$nextID = 0; // this will reset it back to first one if you push next. , or disable it, or set it count($emp) so it doesn't go passed the end
}
?>

<body>
The employee name is: <?php echo $emp[$empID] ?>
