The following mapping is used: - `FIN` => Frame::isFinal(): bool - `RSV1` => none - `RSV2` => none - `RSV3` => none - `OPCODE` => Frame::getOpcode(): int - `MASK` => Frame::isMasked(): bool - `PAYLOAD_LENGTH` => Frame::getPayloadLength(): int - `MASKING_KEY` => Frame::getMaskingKey(): string - `PAYLOAD_DATA` => Frame::getPayload(): string #### Additional functionallity [](#additional-functionallity) There are a few functions added to the Frame for ease of use: - **Frame::isClosing(): bool** => is true when opcode = `0x8` - **Frame::isControl(): bool** => is true when opcode is for contol - **Frame::isNonControl(): bool** => is true when opcode is not for contol #### Events [](#events) The websocket makes use of the symfony event dispatcher. Because of this, each incomming dataframe wil dispatch an event. This event can be used to react on incomming frames. The following is a list of events that can be listened to: Event classReasonHandshakeEventfirst data sent over a new connection will be treated as handshake requestConnectEventnew connection (handshake is already done when this event is triggered)DataEventreceived data (triggered when data is received)FrameEventreceived frame (triggered when a frame is received)MessageEventreceived message (only works when the FrameEventSubscriber is an active listener, triggered when a frame is received with TEXT opcode)DisconnectEventdisconnected (triggered when a connection is disconned)For all events to be dispatched there are 4 event dispatchers. The following is a list of the dispatchters and their in-/outgoning events: DispatcherIncomming eventsOutgoing eventsPurposeHandshakeEventSubscriberHandshakeEventConnectEventHandle handshake and dispatch a connect event when successfullConnectionEventSubscriberConnectEvent, DisconnectEventDataEvent, DisconnectEventHandle connection and map connection eventsDataEventSubscriberDataEventFrameEventParse incomming data to a frame and dispatch as frame eventFrameEventSubscriberFrameEventMessageEventHandle incomming frame event and dispatch a Message event if the opcode is TEXT### Running the example [](#running-the-example) There is a simple chat application included in this project. To run this, use the following commands: ``` php example/socket.php php -S 127.0.0.1:8080 -t ./example/web ``` **You must run both commands separate from each other** ### Known issues [](#known-issues) 1. Fragmentations is not supported yet 2. Encode function of the encoder does not yet support masking 3. Strings longer than 65536 cannot be received due to buffering ### Health Score 18 — LowBetter than 8% of packages Maintenance0 Infrequent updates — may be unmaintained Popularity6 Limited adoption so far Community7 Small or concentrated contributor base Maturity49 Maturing project, gaining track record Bus Factor1 Top contributor holds 100% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
