调用我的函数而不是匿名函数

我有一个匿名函数onconnect事件中运行。如何调用我的函数OnConnect()而不是匿名函数？

$this->server->on("connect", function (WebSocketTransportInterface $user) {
            $this->Logger->notice((" Connected " . $user->getIp()));
        });

和

public function OnConnect(WebSocketTransportInterface $user) {
    $this->Logger->notice((" Connected " . $user->getIp()));     
}

类似的东西

 $this->server->on("connect", OnConnect($user));
