客戶端連線

ws = new WebSocket("ws://127.0.0.1:8000");
ws.onopen = function() {
    alert("連線成功");
    ws.send('uid1');
};
ws.onmessage = function(e) {
    alert(e.data);
};

服務端主動傳送訊息

public function send()
{
    // 建立socket連線到內部推送埠
    $client = stream_socket_client('tcp://127.0.0.1:'.C('WS_INNER_PORT'), $errno, $errmsg, 1);
    // 推送的資料，包含uid欄位，表示是給這個uid推送
    $data = array('uid' => '', 'data' => JsonUtil::jsonEncode(['name'=>'張三','age'=>15]));
    // 傳送資料，注意8001埠是Text協議的埠，Text協議需要在資料末尾加上換行符
    fwrite($client, json_encode($data) . "\n");
    // 讀取推送結果
    $res = trim(fread($client, 8192),"\n");
    $this->json->ok($res);
}
