Where does the data come from? Where does it go? Why isn't this an endless recursive loop? Why has this worked for three years?

My friend wrote this code recently
<?php
// This code supposed to find adjacent items of a specific one
// $list is an array of ids
// $itemToSearch is an id that might be in the $list
foreach ($list as $item) {
next($list);
if ($item == $itemToSearch) {
break;
}
$previousItem = $item;
}
$nextItem = current($list);
The $list variable is a list of ids, e.g [1, 2, 3, 4, 5] The $itemToSearch is an id that might be in $list
