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.

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); ?> |
