(PHP 4, PHP 5)

array_reverse — Return an array with elements in reverse order

Description

array array_reverse ( array $array [, bool $preserve_keys ] )

The input array.

preserve_keys

Return Values

Returns the reversed array.

Examples

Example #1 array_reverse() example

<?php
$input  = array("php", 4.0, array("green", "red"));
$result = array_reverse($input);
$result_keyed = array_reverse($input, true);
?>

This makes both $result and $result_keyed have the same elements, but note the difference between the keys. The printout of $result and $result_keyed will be: 

Array
(
    [0] => Array
        (
            [0] => green
            [1] => red
        )

    [1] => 4
    [2] => php
)
Array
(
    [2] => Array
        (
            [0] => green
            [1] => red
        )

    [1] => 4
    [0] => php
)
