Ds\Map::putAll — Associates all key-value pairs of a traversable object or array

説明

public function Ds\Map::putAll(mixed $pairs): void

Associates all key-value pairs of a traversable object or array.

注意:
Keys of type object are supported. If an object implements Ds\Hashable, equality will be determined by the object's equals function. If an object does not implement Ds\Hashable, objects must be references to the same instance to be considered equal.

パラメータ

pairs: traversable object or array.

例

例1 Ds\Map::putAll() example

<?php
$map = new \Ds\Map();

$map->putAll([
    "a" => 1,
    "b" => 2,
    "c" => 3,
]);

print_r($map);
?>

上の例の出力は、たとえば以下のようになります。

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
        )

)
