范例

Example #1 Ds\Map::merge() example


<?php
$map = new \Ds\Map(["a" => 1, "b" => 2, "c" => 3]);

print_r($map->merge(["a" => 10, "e" => 50]));
?>

以上例程的输出类似于：

Ds\Map Object
(
    [0] => Ds\Pair Object
        (
            [key] => a
            [value] => 10
        )

    [1] => Ds\Pair Object
        (
            [key] => b
            [value] => 2
        )

    [2] => Ds\Pair Object
        (
            [key] => c
            [value] => 3
        )

    [3] => Ds\Pair Object
        (
            [key] => e
            [value] => 50
        )

)
