Beispiel #1 Ds\Map::__construct() example

<?php
$map = new \Ds\Map();
var_dump($map);

$map = new \Ds\Map(["a" => 1, "b" => 2, "c" => 3]);
var_dump($map);
?>

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

object(Ds\Map)#1 (0) {
}
object(Ds\Map)#2 (3) {
  [0]=>
  object(Ds\Pair)#1 (2) {
    ["key"]=>
    string(1) "a"
    ["value"]=>
    int(1)
  }
  [1]=>
  object(Ds\Pair)#3 (2) {
    ["key"]=>
    string(1) "b"
    ["value"]=>
    int(2)
  }
  [2]=>
  object(Ds\Pair)#4 (2) {
    ["key"]=>
    string(1) "c"
    ["value"]=>
    int(3)
  }
}
