PHP | Ds\Map putAll() function

The Ds\Map::putAll() function is an inbuilt function in PHP, which is used to associates all key-value pairs of a traversable object or array.

Syntax:

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

Parameter: This function accepts single parameter $pairs which is the traversal object or array.

Return value: It does not return any value.

Below programs illustrate the Ds\Map::putAll() function in PHP:

Program 1:

<?php

// Declare a new map
$map = new \Ds\Map();

$map->putAll([
    "a" => "Geeks",
    "b" => "for",
    "c" => "Geeks"
]);

print_r($map);

// Declare a new map
$map = new \Ds\Map();

$map->putAll([
    "b" => "Computer",
    "e" => "Science",
    "f" => "Portal"
]);

print_r($map);

?>

Output:

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

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

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

)
Ds\Map Object
(
    [0] => Ds\Pair Object
        (
            [key] => b
            [value] => Computer
        )

    [1] => Ds\Pair Object
        (
            [key] => e
            [value] => Science
        )

    [2] => Ds\Pair Object
        (
            [key] => f
            [value] => Portal
        )

)

Program 2:

<?php

// Declare a new map
$map = new \Ds\Map();

$map->putAll([
    "Geeks1" => "computer",
    "Geeks2" => "science",
    "Geeks3" => 5,
    "Geeks4" => 20
]);

var_dump($map);

// Declare a new map
$map = new \Ds\Map();

$map->putAll([
    "x" => "A",
    "y" => "B",
    "z" => "C"
]);

var_dump($map);

?>

Output:

object(Ds\Map)#1 (4) {
  [0]=>
  object(Ds\Pair)#2 (2) {
    ["key"]=>
    string(6) "Geeks1"
    ["value"]=>
    string(8) "computer"
  }
  [1]=>
  object(Ds\Pair)#3 (2) {
    ["key"]=>
    string(6) "Geeks2"
    ["value"]=>
    string(7) "science"
  }
  [2]=>
  object(Ds\Pair)#4 (2) {
    ["key"]=>
    string(6) "Geeks3"
    ["value"]=>
    int(5)
  }
  [3]=>
  object(Ds\Pair)#5 (2) {
    ["key"]=>
    string(6) "Geeks4"
    ["value"]=>
    int(20)
  }
}
object(Ds\Map)#5 (3) {
  [0]=>
  object(Ds\Pair)#1 (2) {
    ["key"]=>
    string(1) "x"
    ["value"]=>
    string(1) "A"
  }
  [1]=>
  object(Ds\Pair)#4 (2) {
    ["key"]=>
    string(1) "y"
    ["value"]=>
    string(1) "B"
  }
  [2]=>
  object(Ds\Pair)#3 (2) {
    ["key"]=>
    string(1) "z"
    ["value"]=>
    string(1) "C"
  }
}
