## Installation

You can install library through Composer:

```javascript

{

    "require": {

        "sokil/php-list": "dev-master"

    }

}

```

## Priority Map

Priority map allows you to specify priority of items and 

iterate through this list in order to priority.

Add elements to list with priority:

```php

set('key1', 'value1', 10);

$list->set('key2', 'value2', 100);

```

Get elements according to priority:

```php

 $value) {

    echo $key . ' - ' . $value;

}

// this will print

//   key2 - value2

//   key1 - value1

```

Get element by key:

```php

set('key1', 'value1', 10);

$list->get('key1');

```

    

## Weight List

Weight list allows you to specify values and relative weights, and randomly

get value according to it's weight.

Imagine that we have three database servers with ip addresses: 10.0.0.1, 10.0.0.2 and 10.0.0.3.

We want to balance connections between nodes with weights 60%, 30% and 10%. So 

most connections goes to server 10.0.0.1, than to 10.0.0.2 and than to 10.0.0.3.

```

 60,

    '10.0.0.2' => 30,

    '10.0.0.3' => 10,

]);

$ipAddress = $list->getRandomValue();

```

    

Now we have address on every request relatively to it's weight.
