Php prev () function

Write your php code

(PHP 3, PHP 4 , PHP 5)

prev -- Rewind the internal array pointer

Syntax

mixed prev ( array &array )

Returns the array value in the previous place that's pointed to by the internal array pointer, or FALSE if there are no more elements.

Warning

If the array contains empty elements then this function will return FALSE for these elements as well. To properly traverse an array which may contain empty elements see the each() function.

prev() behaves just like next(), except it rewinds the internal array pointer one place instead of advancing it.

Example 1. Example use of prev() 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';
?>
