NEXT(3) 1 NEXT(3)
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).
