使用

安装

composer require teamones/dbevent-observer

被观察者装载接口和观察者实现

<?php

namespace teamones\dbeventObserver\examples;

use teamones\dbeventObserver\interfaces\SplSubject;
use teamones\dbeventObserver\SplSubjectEnforcer;

class ExampleModel implements SplSubject
{
    use SplSubjectEnforcer;
}

业务观察者

<?php

namespace teamones\dbeventObserver\examples;

use teamones\dbeventObserver\interfaces\SplObserver;
use teamones\dbeventObserver\interfaces\SplSubject;

class ExampleObServer implements SplObserver
{
    public function update(SplSubject $subject): void
    {
        // TODO: Implement update() method.
        // 打印修改的数据 根据要修改的数据,进行业务处理
        var_dump($subject->getSplUpdateData());
    }
}
