[PHP知识库]php生成不重复的订单号

<?php


  /**
     * 使用雪花算法生成订单ID
     * @return string
     * @throws \Exception
     */
    function getNewOrderId(string $prefix = 'wx')
    {
        $snowflake = new \Godruoyi\Snowflake\Snowflake();
        $swooleSequenceResolver = new \Godruoyi\Snowflake\SwooleSequenceResolver();
        //32位
        if (PHP_INT_SIZE == 4) {
            $id = abs($snowflake->setSequenceResolver($swooleSequenceResolver)->id());
        } else {
            $id = $snowflake->setStartTimeStamp(strtotime('2021-08-02') * 1000)->setSequenceResolver($swooleSequenceResolver)->id();
        }
        return $prefix . $id;
    }

通过composer加载组件：

"godruoyi/php-snowflake": "^1.0",
