next - Advance the internal array pointer of an array

SYNOPSIS
mixed next (array &$array) DESCRIPTION
next(3) behaves like current(3), with one difference. It advances the internal array pointer one place forward before returning the element value. That means it returns the next array value and advances the internal array pointer by one. PARAMETERS
o $array - The array being affected. RETURN VALUES
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. Warning This function may return Boolean FALSE, but may also return a non-Boolean value which evaluates to FALSE. Please read the section on Booleans for more information. Use the === operator for testing the return value of this function. EXAMPLES
Example #1 Example use of next(3) and friends <?php $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'; ?> NOTES
Note You won't be able to distinguish the end of an array from a boolean FALSE element. To properly traverse an array which may contain FALSE elements, see the each(3) function. SEE ALSO
current(3), end(3), prev(3), reset(3), each(3). PHP Documentation Group NEXT(3)
