# next

(PHP 3, PHP 4, PHP 5)

next -- Advance the internal array pointer of an array

## Description

mixed next ( array &array )

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.

next() behaves like current(), 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. If advancing the internal array pointer results in going beyond the end of the element list, next() returns `FALSE`.

Warning
This function may return Boolean `FALSE`, but may also return a non-Boolean value which evaluates to `FALSE`, such as 0 or "". Please read the section on Booleans for more information. Use the === operator for testing the return value of this function.

> 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() function.

Example 1. Example use of next() 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'; ?>`

See also current(), end(), prev(), reset(), and each().
