雪花算法

功能介紹

生成唯一編號(hào)

相關(guān)class位置

• SnowFlake
  • namespace: EasySwoole\Utility\SnowFlake

核心對(duì)象方法

make

生成基于雪花算法的隨機(jī)編號(hào)

• mixed $dataCenterID 數(shù)據(jù)中心
• mixed $workerID 任務(wù)進(jìn)程

static function make($dataCenterID = 0, $workerID = 0)

unmake

反向解析雪花算法生成的編號(hào)

• mixed $snowFlakeId 編號(hào)

static function unmake($snowFlakeId)

require './vendor/autoload.php';

$str = \EasySwoole\Utility\SnowFlake::make(1,1);//傳入數(shù)據(jù)中心id(0-31),任務(wù)進(jìn)程id(0-31)
var_dump($str);
var_dump(\EasySwoole\Utility\SnowFlake::unmake($str));
