Below programs illustrate the Ds\Map::put() function in PHP:
Program 1:
<?php // Declare a new map $map = new \Ds\Map();
$map ->put( "a" , "Geeks" );
$map ->put( "b" , "for" );
$map ->put( "c" , "Geeks" );
// Display output print_r( $map );
// Declare a new map $map = new \Ds\Map();
$map ->put( "a" , "Computer" );
$map ->put( "b" , "Science" );
$map ->put( "c" , "Portal" );
// Display output 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] => a [value] => Computer ) [1] => Ds\Pair Object ( [key] => b [value] => Science ) [2] => Ds\Pair Object ( [key] => c [value] => Portal ) )
Program 2:
<?php // Declare a new map $map = new \Ds\Map();
$map ->put( "Geeks1" , "computer" );
$map ->put( "Geeks2" , "science" );
$map ->put( "Geeks3" , 5);
$map ->put( "Geeks3" , 20);
// Display result var_dump( $map );
?> |
Output:
object(Ds\Map)#1 (3) { [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(20) } }
