Examples

Example #1 array_reverse() example

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

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
)
