\#Alea

A tiny library to select a random element from a weighted list.

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

[](#installation)

### With composer

[](#with-composer)

If you use [composer](http://getcomposer.org/), you just need to add `lortabac/alea` to your `composer.json` file.

```
{
    "require": {
        "lortabac/alea": "dev-master"
    }
}

```

### Manual installation

[](#manual-installation)

1. Copy the files in the `src` directory into your project.
2. Include the class you need (`WeightedList.php` or `Dice.php`).

Usage
-----

[](#usage)

### Weighted list

[](#weighted-list)

In weighted list mode, a relative weight is assigned to each element.

```
$criteria = [
	['foo', 50],
	['bar', 30],
	['baz', 20]
];

$weightedList = new Alea\WeightedList($criteria);
$element = $weightedList->getItem();
```

### Dice

[](#dice)

In dice mode, each element has a specific range. Only the upper limit is specified. The first range always starts from 1.

```
$criteria = [
    ['foo', 6], // from 1 to 6
    ['bar', 8], // 7 and 8
    ['baz', 12] // from 9 to 12
];

$dice = new Alea\Dice($criteria);
$element = $dice->getItem();
```

You can optionally include the dice roll. In this case the result is given as an associative array.

```
$itemData = $dice->getItem(Alea\Dice::INCLUDE_ROLL);
print_r($itemData);

/*
Array
(
    [roll] => 8
    [item] => bar
)
*/
```
