The square bracket operator does not seem to alter the array pointer:

<?php

$foo = range(0, 99);

var_dump(next($foo));
var_dump(next($foo));

$foo[50];

var_dump(next($foo));

?>

.... prints this:

int(1)
int(2)
int(3)

Array pointers are not very practical but I suppose the are not widely
used anyway.
