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 |
If the array contains empty elements, or elements that have a key
value of 0 then this function will return a value which
evaluates to FALSE for these elements as well (see converting to boolean
and the type comparison tables
for more information). To properly traverse an array which
may contain empty elements or elements with key values of 0 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';
?>
