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.

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" } }
