请问这两种push有什么区别

$server->push($frame->fd, "this is server");

$this->server->push($frame->fd, "this is server");

代码中这两种push区别在哪儿呢？
我测试了下两个对象 json_encode 是相等的

{{{
<?php

class WebsocketTest {
    
	public $server;
    public function __construct() {
        $this->server = new swoole_websocket_server("0.0.0.0", 9501);
		
        $this->server->on('open', function (swoole_websocket_server $server, $request) {
			echo "server: handshake success with fd{$request->fd}\n";
		});
		
        $this->server->on('message', function (swoole_websocket_server $server, $frame) {
			echo "receive from {$frame->fd}:{$frame->data},opcode:{$frame->opcode},fin:{$frame->finish}\n";
			
			$encode1= json_encode($server);
			$encode2= json_encode($this->server);
			if($encode1 != $encode2){
				echo '有区别';
			}
			
			$server->push($frame->fd, "this is server");
			
			$this->server->push($frame->fd, "this is server");
		});
		
        $this->server->on('close', function ($ser, $fd) {
			echo "client {$fd} closed\n";
		});
		
        $this->server->on('request', function ($request, $response) {
			// 接收http请求从get获取message参数的值，给用户推送
			// $this->server->connections 遍历所有websocket连接用户的fd，给所有用户推送
			foreach ($this->server->connections as $fd) {
				$this->server->push($fd, $request->get['message']);
			}
		});
		
        $this->server->start();
    }
}
new WebsocketTest();
?>
}}}
