The **`Map` class** in PHP is a collection of key-value pairs. The structure of a `Map` is similar to an array in terms of the #key# sequence :insertion order is preserved #key#, performance, and memory efficiency.

The **`last()` function** is used to return the last key-value pair in a map.


#   
#  Syntax

The following is the function prototype:

```php
Ds\Pair public Ds\Map::last()
```

#   
## Parameters and return value

- The `last()` function does not take any input parameters.

- The function returns the last key-value pair in the map.

##  
## Code
Let’s run the following code to see how the `last()` function works.



<?php

// Creating a Map
$map = new \Ds\Map(["0" => "a", 
            "1" => "b", "2" => "c", "3" => "d", "4" => "e", "5" => "f"]);
  
print_r($map->last());
  
?>


In the example above, we create a simple map. Using the `last()` function, we are able to directly print the last key-value pair in the map.
