Returns a shallow copy of the map.
示例 #1 Ds\Map::copy() example
<?php
$map = new \Ds\Map([
"a" => 1,
"b" => 2,
"c" => 3,
]);
print_r($map->copy());
?>
以上示例的输出类似于:
Ds\Map Object ( [0] => Ds\Pair Object ( [key] => a [value] => 1 ) [1] => Ds\Pair Object ( [key] => b [value] => 2 ) [2] => Ds\Pair Object ( [key] => c [value] => 3 ) )
