# array_reverse

(PHP 4, PHP 5)

array_reverse — Return an array with elements in reverse order

### Description

array array_reverse ( array `$array` [, bool `$preserve_keys` = false ] )

Takes an input `array` and returns a new array with the order of the elements reversed.

### Parameters

`array`

  The input array.

`preserve_keys`

  If set to `TRUE` keys are preserved.

### Return Values

Returns the reversed array.

### Changelog

Version | Description
--- | ---
4.0.3 | The `preserve_keys` parameter was added.

### 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
    )
