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

Ds\Map::putAll

(PECL ds >= 1.0.2)

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

说明

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

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

Note:

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.

参数

pairs: traversable object or array.

返回值

没有返回值。

范例

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

 <?php
$map = new \Ds\Map();

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

print_r($map);
?>

以上例程的输出类似于：

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
        )

)
