Actually, foreach() creates a copy of the mentioned array, and the array
pointer of the original array is not modified. Very useful to know if you
append entries to the array you're foreach()-ing and pulling your hair out
why foreach() doesn't iterate through those new entries...
An way of going through the array independent of the actual values (since
using end() relies on unique values):
$n = count($numbers);
$i = 0;
foreach ($numbers as $number) {
$i ++;
if ($i == $n) {
// Last element...
} else {
// Not the last element...
}
}
