La función Ds\Map::putAll() es una función incorporada en PHP, que se utiliza para asociar todos los pares clave-valor de un objeto o array transitable.
Sintaxis:
void public Ds\Map::putAll( mixed $pairs )
Parámetro: esta función acepta un solo parámetro $pares, que es el objeto transversal o la array.
Valor devuelto: No devuelve ningún valor.
Los siguientes programas ilustran la función Ds\Map::putAll() en PHP:
Programa 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); ?>
Producción:
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
)
)
Programa 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); ?>
