            Symfony Doctrine EntityManager not refreshing properly
            Asked 2022-Mar-14 at 13:18

            I have a ratchet WebSocket server, whose entityManager is initialized from the backend. However, if some changes happen from one of the front-ends since the state of the entityManager of the WebSocket server is different from the backend, the new changes are not reflected in the data that is served by the WebSocket server.

            For this purpose, I wrote some listeners on the backend that listen for changes in these entities in and then send a request to the server like so:

            Doctrine uses the identity map

            The websocket server is a daemon and all cleanup tasks are the responsibility of the developer

            Create two aggregated virtual tables from one table and join
            Asked 2021-Dec-23 at 10:03

            I want to build a query based one table. From this one table I want to create two virtual tables based on an count aggregation query. In my example it would split to original table into a table where Xbox Games per Player are counted and one where Playstation Games per player are counted. Then the results of the queries are joined based on the PlayerID.

            Parsing deeply nested XML into dataframe with python - struggling with deeper elements

            I'm attempting to parse out a fairly nested XML file. I've spent the last few hours trying to find a solution with no luck. I'm not sure if the issue is with namespaces, or needing to findall within the loop.

            I am able to extract the higher level elements but the deeper nested elements are not being extracted. I am looking to export Part_number, manufacturer_name, name, Product and Retail to a df.

            Is it possible to call http API by websocket?
            Asked 2021-Aug-31 at 13:24

            I was asked me to make an api call using websocket with php Ratchet at work. Since I'm totally unfamilier with websocket so I googled and watched youtube videos to solve this problem, but The more I searched, the more I felt it is impossible to call api with websocket.

            Am I missing something or is it really impossible to call api by websocket? If it is possible, can you please show me an example how to do it

            I know i might sound awkward since I don't have a solid understanding of websockets, English isn't even my first language, but i'm really desperate please help me

            A REST API is fundamentally different from a WebSocket API.

            REST API

            Calls are made through HTTP(S). You can use AJAX (see here: https://en.wikipedia.org/wiki/Ajax_(programming)) to access HTTP endpoints directly from the browser. In JavaScript you would use the Fetch-API (see here: https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API) to make calls. Each and every call is stateless per definition. Cookies and special headers must be send with every request to create a context (e.g. user that is logged in).

            Can't establish a connection with javascript to a secure websocket server
            Asked 2021-Aug-24 at 09:53

            My development environment is this:

            • OS: Microsoft Windows 10
            • PHP framework: Laravel 8.0
            • PHP version 7.4
            • Websocket server: cboden/ratchet 0.4.3
            • WAMP server 3.2.0 (Apache 2.4.41)
            • Firefox 91.0.1 (64-bit) / chrome

            I created a new Laravel app to implement a Secure Websocket Server and get connected to it using plain javascript on the client side (Laravel blade file). The websocket server works fine, as far as I can see it running, but the web browser is not able to connect, as seen on this image:

            I have tried using different URLs, with and without port number, but to no avail. I created a SSL certificate and private key files, using openssl.exe tool, and put them in the command folder for testing purposes.

            This is my handle code for the Secure Websocket Server:

            You are surely trying to connect to the wrong destination. It says wss:///ssa/wss/, but probably it should be wss://your.site.domain/ssa/wss/ .

            So let's look at front end code and find out what's wrong with it.

            How to use html5 websockets within sharedworkers
            Asked 2021-Jun-25 at 08:37

            After checking similar questions on stackoverflow I did not find anything much helpful for what I want to do in my project. Reading and researching I successfully made the application work having multiple connections to my Ratchet PHP websocket server, but I noticed every time the user reloaded a page or opened a link in a new tab, the client websocket got disconnected and then reconnected again.

            So, I wonder how to get only one persistent connection to a WebSocket Server, for multiple users, in a web application using a Sharedworker.

            What I have in the client side is this:



            Answered 2021-Jun-25 at 08:37

            Ok after reading, researching and trying different things and code samples, I came to this solution:

            The client side (browser) should have the connection to a Sharedworker. The sharedworker is a separated javascript file containing the core of the sharedworker and whatever other JS code that needs to be executed within it. I first tested the sharedworker to work fine with the browser tabs, counting the number of opened tabs per user and sharing messages to one user, and then to a group of users. Once the communication between the browser and the Sharedworker passed those tests I added the websocket code to the body of the Sharedworker JS file.

            In the end, the client side (browser) looks like this:

            Word of Caution

            It is strongly discouraged from using PHP with Symfony and/or Doctrine for any long-running background processes (daemon), that listens for WebSocket (or other) connections, using Ratchet/ReactPHP style features in any production/real-world environments. PHP was not designed to run as a daemon. As such, without proper planning, the process will crash with either a Doctrine Connection exception with the MySQL Server Has Gone Away error or from memory leaks caused by maintaining the Entity Manager, Symfony service definitions and logger overflows.

            Using PHP as a daemon would require implementing unintuitive workarounds, such as a Messenger Queue (causes long delays between responses) or Lazy Proxy objects (causes code-level maintainability issues) and additional background processes, like supervisor and/or cron jobs to circumvent the inherent issues and recover from crashes.

            See below for a NodeJS alternative solution, to avoid the PHP daemon issues.

            Provided you are using the default autowire configuration for your config/services.yaml and ScoreHandler is not in one of the excluded paths, the following options are feasible using dependency injection.

            Laravel + Ratchet: Pushing notifications to specific clients
            Asked 2021-Jun-03 at 08:03

            I am new to websockets and I want to implement such service in my Laravel application. I have already read several posts/pages about this topic, but none explains what I need to do. All of them show how to create an "Echo" websocket server, where the server only responds to messages received from clients, which is not my case.

            As a starting base I used the code provided at:


            Where the websocket server is ran from the command line or another console. The server has its own class to define it and imports the WebSocketController class (MessageComponentInterface), which contains the classic WebSocket server events (onOpen, onMessage, onClose, onError).

            All that works fine as is but, how can I "tell" the WebSocket Server to send a message to a specific connection (client) from another class, which also belong to another namespace?. This is the case of a notification or event, where new web content must be sent to that specific client. There are no subscriptions nor publications on the way from the client side.

            As @Alias asked in his post Ratchet PHP - Push messaging service I obviously cannot create a new instance of the Websocket server or its events management class, so what would be the best approach to send content or messages to the client?

            As you all can see, the communication is only in one way: from the WebSocket Server to the client(s) and not the opposite. I already have a notification class and a listener class prepared for this but, I still don't know how to address the communication with clients from the handle() method:

            Ok, after studying and researching a lot, I could post an answer to a similar question in:

            How to send a message to specific websocket clients with symfony ratchet?

            This is the solution I found, according to what I wrote in my second comment in this thread.

            I installed cboden/Ratchet package for the websocket server using composer. I needed to send notifications to a user/group of users, or update the UI, when an event is fired in the backend.

            What I did is this:

            1) Installed amphp/websocket-client package using composer.

            2) Created a separated class in order to instantiate an object that could get connected to the websocket server, send the desired message and disconnect:
