示例 #1 Ds\Map::pairs() example
<?php
$map = new \Ds\Map(["a" => 1, "b" => 2, "c" => 3]);
var_dump($map->pairs());
?>
以上示例的输出类似于:
object(Ds\Map)#8 (3) { [0]=> object(Ds\Pair)#5 (2) { ["key"]=> string(1) "a" ["value"]=> int(1) } [1]=> object(Ds\Pair)#6 (2) { ["key"]=> string(1) "b" ["value"]=> int(2) } [2]=> object(Ds\Pair)#7 (2) { ["key"]=> string(1) "c" ["value"]=> int(3) } } p
