I see some questions like "how can I know if an array has a next value without changing its
internal pointer" and some pretty complicated responses that DO work mind you and in some cases
you'll need them...
But suppose you just need a different action within a foreach loop when reaching the final item:
(it won't be usefull in every situation, but in most it will)
$numOfItems = count($someArray);
$counter = 0;
foreach ($someArray as $key => value){
$counter += 1;
if ($counter <> $numOfItems){
//here all next items exist
} else {
//final item
}
}
