About the registration tree mode in Workerman

The following column Workerman Tutorial will introduce you to the registration tree mode in Workerman. I hope it will be helpful to friends in need!

Registration tree mode is to hang the object into the attribute array of a class. Next time, it will be fetched directly from this array to keep it globally unique, usually at the project entrance. Useful during initialization.

In workerman, the very beginning is the application of registration tree mode. The following is its simulation

<?php
class Worker{
    protected static $_workers=array();
    public function __construct()
    {
        $this->workerId=spl_object_hash($this);
        static::$_workers[$this->workerId]=$this;
    }
    public static function runAll(){
        foreach (static::$_workers as $worker) {
            var_dump($worker);
        }
    }
}
new Worker();
new Worker();
Worker::runAll();

In the constructor of Worker, hang the current new object into the static variable attribute array of the Worker class, and fetch it directly from that array the next time it is used
