next
(PHP 4, PHP 5, PHP 7, PHP 8)
Advance the internal pointer of an array
Description
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.
Parameters
arrayThe
arraybeing 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.

Examples
Example use of next() and friends
<?php
$transport = array('foot', 'bike', 'car', 'plane');
echo $mode = current($transport), PHP_EOL; // $mode = 'foot';
echo $mode = next($transport), PHP_EOL; // $mode = 'bike';
echo $mode = next($transport), PHP_EOL; // $mode = 'car';
echo $mode = prev($transport), PHP_EOL; // $mode = 'bike';
echo $mode = end($transport), PHP_EOL; // $mode = 'plane';
?>Notes
The end of an array is indistinguishable from a bool false element. To properly traverse an array which may contain false elements, 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 null.
