# Examples

Example #1 Vector

`<?php
$vector = new \Ds\Vector();
$vector->push('a');
$vector->push('b', 'c');
$vector[] = 'd';
print_r($vector);
?>`

The above example will output something similar to:

    Ds\Vector Object
    (
        [0] => a
        [1] => b
        [2] => c
        [3] => d
    )

Example #2 Map

`<?php
$map = new \Ds\Map();
$map->put('a', 1);
$map->put('b', 2);
$map['c'] = 3;
print_r($map);
?>`

The above example will output something similar to:

    Ds\Map Object
    (
        [0] => Ds\Pair Object
            (
                [key] => a
                [value] => 1
            )

        [1] => Ds\Pair Object
            (
                [key] => b
                [value] => 2
            )

        [2] => Ds\Pair Object
            (
                [key] => c
                [value] => 3
            )

    )
