array_reverse

(PHP 4 )

array_reverse -- Return an array with elements in reverse order

Description

array array_reverse ( array array [, bool preserve_keys])

array_reverse() takes input array and returns a new array with the order of the elements reversed, preserving the keys if preserve_keys is TRUE.

範例 1. array_reverse() example

$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
)




注: The second parameter was added in PHP 4.0.3.
