&$array) : mixed

Returns the array value in the next place that's pointed to by the
internal array pointer, or
FALSE if there are no more elements.
This function may

Example #1 Example use of next() and friends
$transport = array('foot', 'bike', 'car', 'plane');
$mode = current($transport); // $mode = 'foot';
$mode = next($transport); // $mode = 'bike';
$mode = next($transport); // $mode = 'car';
$mode = prev($transport); // $mode = 'bike';
$mode = end($transport); // $mode = 'plane';
Note: The end of an array is indistinguishable from a boolean
FALSEelement. To properly traverse an array which may contain
FALSEelements, see the foreach() function. To still use next() and properly check if the end of the array has been reached, verify that the key() is
