<?php
namespace tinymeng\tools\core;

/**
 * 单例

trait Singleton
{
    private $config;

    /**
     * @var null
     */
    private static $instance = null;

    public function __construct($config=[]){
        $this->config = $config;
    }

    private function __clone(){}

    public function __sleep(): array
    {
        //重写__sleep方法，将返回置空，防止序列化反序列化获得新的对象
        return [];
    }

    protected static function init($gateway, $config=[])

The parameter $gateway is not used and could be removed.

    {
        if (!self::$instance instanceof static) {
            self::$instance = new static($config);

It seems like new static($config) of type tinymeng\tools\core\Singleton is incompatible with the declared type null of property $instance.

        }
        return self::$instance;
    }

    /**
     * Description:  __callStatic

    public static function __callStatic($gateway, array $config=[])
    {
        return self::init($gateway, ...$config);

$config is expanded, but the parameter $config of tinymeng\tools\core\Singleton::init() does not expect variable arguments.

    }
