php-finding next array value in a for-loop

Question

PHP question. Running the values of an array through a for loop, and need to find the next value, as a reference based on the value currently in the loop.

I created the array below:

$item_number: A12345-AFA-21-AEA-22-APA-23
$items = explode("-", $item_number);

i'm using a for loop that starts at AFA:

for ($i=1; $i<$itemcount; $i++)

setting the current loop value to $item.

$item = $items[$i];

How do I get the next value in the array? here is what seems the most logical to me.. but doesn't seem to work.

$next = $items[$i+1]

How do I get to the next array value?

Answer 1

It should work, maybe just add isset($items[$i+1]) or if($i < $itemcount - 1) before using it, because on last element it will crash..

Answer 2

This should work, but keep in mind that an array starts at 0 not 1, so you need to change it to:

for ($i=0; $i<$itemcount; $i++){
    $item = $items[$i];
    $next = $items[$i+1];
}
