Let's see this loop:
$tomb = [1, 2, 3];
foreach ($tomb as $x) {
echo $x . '<br/>';
}
var_dump(current($tomb));
It displays:
1
2
3
bool(false)
It's correct, because the internal pointer advanced on every iteration, and on end it points over on array, current() returns false.
But this:
$tomb = [1, 2, 3];
foreach ($tomb as $x) {
echo $x . ' : ' . current($tomb) . '<br/>';
}
var_dump(current($tomb));
Displays:
1 : 2
2 : 2
3 : 2
int(2)
Why? The internal pointer not advanced on every iteration, only once. The documentaion under current() says: "It does not move the pointer i n any way". Why the internal pointer only advanced by one, and not all of iterations? And why the current() affects the internal pointer?
