Arp\\TennisGame
===============

[](#arptennisgame)

About
-----

[](#about)

A PHP solution to the Tennis scoring challenge.

Installation
------------

[](#installation)

Installation via [composer](https://getcomposer.org).

```
require alex-patterson-webdev/tennis-game ^1

```

Usage
-----

[](#usage)

In order to calculate the Tennis score, first create a new instance of the `Arp\TennisGame\TennisGame` class.

```
use Arp\TennisGame\TennisGame;
$tennisGame = new TennisGame();

```

Once created, we can record scores for `PlayerOne` and `PlayerTwo` by calling either `playerOneWinsShot()` or `playerTwoWinsShot()`. Internally the `TennisGame` class will keep a record of each player's score, regardless of the order of the winning shots.

```
$tennisGame->playerOneWinsShot(); // Increase PlayerOne score by 1 point
$tennisGame->playerTwoWinsShot(); // Increase PlayerOne score by 1 point

```

By default, score for both players start at a value of `love` (zero). At any time we can review the score of each of the players by calling the `renderScore()` method. The score for both players will be returned as a string, `x-y`where `x` represents the first players' score and `y` represents the seconds players' score.

```
echo $tennisGame->renderScore(); // output string 'love-love'

$tennisGame->playerOneWinsShot();
echo $tennisGame->renderScore(); // output string 'fifteen-love'

$tennisGame->playerTwoWinsShot();
echo $tennisGame->renderScore(); // output string 'fifteen-fifteen'

```

In accordance with the rules of Tennis, when players tie and have both reached a score of at least `forty`, then the result of the call to `renderScore()` will be `deuce`, indicating the scores are level.

```
$tennisGame->playerOneWinsShot();
$tennisGame->playerOneWinsShot();
$tennisGame->playerOneWinsShot();

$tennisGame->playerTwoWinsShot();
$tennisGame->playerTwoWinsShot();
$tennisGame->playerTwoWinsShot();

echo $tennisGame->renderScore(); // output string 'deuce'

```

If the score is a tie at `deuce`, players must then score 1 additional point to gain an `advantage`. In these cases, calls to method `renderScore()` will display the player who has the current advantage.

```
$tennisGame->playerOneWinsShot(); // 15
$tennisGame->playerOneWinsShot(); // 30
$tennisGame->playerOneWinsShot(); // 40

$tennisGame->playerTwoWinsShot(); // 15
$tennisGame->playerTwoWinsShot(); // 30
$tennisGame->playerTwoWinsShot(); // 40 (Deuce)
$tennisGame->playerTwoWinsShot(); // advantage PlayerOne

echo $tennisGame->renderScore(); // output string 'advantage PlayerTwo';

```

In order to win the game, players must have a score which exceeds `forty` points and have at least two points more than the competing player. Calls to `renderScore()` will show the name of the player who is the winner.

```
$tennisGame->playerOneWinsShot(); // 15

$tennisGame->playerTwoWinsShot(); // 15
$tennisGame->playerTwoWinsShot(); // 30
$tennisGame->playerTwoWinsShot(); // 40
$tennisGame->playerTwoWinsShot(); // win

echo $tennisGame->renderScore(); // output string 'win PlayerTwo';

```
