### Introduction（介绍）
用 PHP 实现几种负载均衡调度算法，详细见 [负载均衡算法](https://www.fanhaobai.com/2018/11/load-balance-round-robin.html) 系列。[fork](https://github.com/fan-haobai/load-balance)
### Scheduling Algorithm （调度算法）
* [普通轮询（general Round Robin）](https://github.com/Tinywan/load-polling/blob/master/src/Robin.php)
* [加权轮询（Weighted Round Robin）](https://github.com/Tinywan/load-polling/blob/master/src/WeightedRobin.php)
* [平滑加权轮询（Smooth Weighted Round Robin）](https://github.com/Tinywan/load-polling/blob/master/src/SmoothWeightedRobin.php)
### Install
```composer log
composer require tinywan/load-balancing
```
### Basic Usage
```php
// 服务器数
$services = [
'192.168.10.1' => 5,
'192.168.10.2' => 1,
'192.168.10.3' => 1,
];
// 使用平滑加权算法 (Smooth Weighted Round Robin)
$robin = new \Robin\SmoothWeightedRobin();
$robin->init($services);
$nodes = [];
$sumWeight = $robin->getSumWeight();
for ($i = 1; $i <= $sumWeight; $i++) {
$node = $robin->next();
$nodes[$i] = $node;
}
var_export($nodes);
// 会生成如下均匀序列
array (
1 => '192.168.10.1',
2 => '192.168.10.1',
3 => '192.168.10.2',
4 => '192.168.10.1',
5 => '192.168.10.3',
6 => '192.168.10.1',
7 => '192.168.10.1',
)
```
