PHP next() Function: Advancing the Internal Array Pointer

The next() function in PHP behaves similarly to current() but first advances the internal array pointer by one position before returning the value. It accepts a single argument, the array whose pointer is to be moved, and returns the value of the next element or FALSE if the end of the array is reached.

Parameter: array – The array whose internal pointer will be affected.

Return value: The value of the next array element, or FALSE when there are no more elements.

Example:

<?php
$transport = array('foot', 'bike', 'car', 'plane');

// Get the first element (current)
$mode = current($transport);

// Move pointer to next element and retrieve it
$mode = next($transport);

// Move pointer again
$mode = next($transport);

// Move pointer to the previous element
$mode = prev($transport);

// Move pointer to the last element
$mode = end($transport);
?>

In this example, next($transport) advances the pointer and returns the subsequent value each time it is called, while prev() moves it backward and end() jumps to the final element.
