PHP next() Function Usage and Example

PHP Array Function Manual

The next() function returns the value of the next array element and moves the array pointer forward by one position.

Syntax

next(array $array);

Definition and Usage

The behavior of next() and current() is similar, but there is one difference. It moves the internal pointer forward before returning the value. This means it returns the value of the next array element and moves the array pointer forward by one position. If there are no more elements, it returns FALSE.

Parameter

Return value

It returns the next element in the array.

Online example

<?php
　　　$input = array('foot', 'bike', 'car', 'plane');
　　　$mode = current($input);　
　　　print "$mode <br　/>";
　　　
　　　$mode = next($input);
　　　print "$mode <br　/>";
　　　
?>

Output result:

foot
bike
