示例 #1 Ds\Map::reversed() example
<?php
$map = new \Ds\Map(["a" => 1, "b" => 2, "c" => 3]);
print_r($map->reversed());
?>
以上例程的输出类似于:
Ds\Map Object ( [0] => Ds\Pair Object ( [key] => c [value] => 3 ) [1] => Ds\Pair Object ( [key] => b [value] => 2 ) [2] => Ds\Pair Object ( [key] => a [value] => 1 ) )
