+# Websocket Client and Server for PHP
+
+[![Build Status](https://github.com/Textalk/websocket-php/actions/workflows/acceptance.yml/badge.svg)](https://github.com/Textalk/websocket-php/actions)
+[![Coverage Status](https://coveralls.io/repos/github/Textalk/websocket-php/badge.svg?branch=master)](https://coveralls.io/github/Textalk/websocket-php)
+
+This library contains WebSocket client and server for PHP.
+
+The client and server provides methods for reading and writing to WebSocket streams.
+It does not include convenience operations such as listeners and implicit error handling.
+
+## Documentation
+
+- [Client](docs/Client.md)
+- [Server](docs/Server.md)
+- [Message](docs/Message.md)
+- [Examples](docs/Examples.md)
+- [Changelog](docs/Changelog.md)
+- [Contributing](docs/Contributing.md)
+
+## Installing
+
+Preferred way to install is with [Composer](https://getcomposer.org/).
+```
+composer require textalk/websocket
+```
+
+* Current version support PHP versions `^7.2|8.0`.
+* For PHP `7.1` support use version `1.4`.
+* For PHP `^5.4` and `7.0` support use version `1.3`.
+
+## Client
+
+The [client](docs/Client.md) can read and write on a WebSocket stream.
+It internally supports Upgrade handshake and implicit close and ping/pong operations.
+
+```php
+$client = new WebSocket\Client("ws://echo.websocket.org/");
+$client->text("Hello WebSocket.org!");
+echo $client->receive();
+$client->close();
+```
+
+## Server
+
+The library contains a rudimentary single stream/single thread [server](docs/Server.md).
+It internally supports Upgrade handshake and implicit close and ping/pong operations.
+
+Note that it does **not** support threading or automatic association ot continuous client requests.
+If you require this kind of server behavior, you need to build it on top of provided server implementation.
+
+```php
+$server = new WebSocket\Server();
+$server->accept();
+$message = $server->receive();
+$server->text($message);
+$server->close();
+```

+# Websocket: Client
+
+The client can read and write on a WebSocket stream.
+It internally supports Upgrade handshake and implicit close and ping/pong operations.
+
+##  Class synopsis
+
+```php
+WebSocket\Client {
+
+    public __construct(string $uri, array $options = [])
+    public __destruct()
+    public __toString() : string
+
+    public text(string $payload) : void
+    public binary(string $payload) : void
+    public ping(string $payload = '') : void
+    public pong(string $payload = '') : void
+    public send(mixed $payload, string $opcode = 'text', bool $masked = true) : void
+    public receive() : mixed
+    public close(int $status = 1000, mixed $message = 'ttfn') : mixed
+
+    public getName() : string|null
+    public getPier() : string|null
+    public getLastOpcode() : string
+    public getCloseStatus() : int
+    public isConnected() : bool
+    public setTimeout(int $seconds) : void
+    public setFragmentSize(int $fragment_size) : self
+    public getFragmentSize() : int
+    public setLogger(Psr\Log\LoggerInterface $logger = null) : void
+}
+```
+
+## Examples
+
+### Simple send-receive operation
+
+This example send a single message to a server, and output the response.
+
+```php
+$client = new WebSocket\Client("ws://echo.websocket.org/");
+$client->text("Hello WebSocket.org!");
+echo $client->receive();
+$client->close();
+```
+
+### Listening to a server
+
+To continuously listen to incoming messages, you need to put the receive operation within a loop.
+Note that these functions **always** throw exception on any failure, including recoverable failures such as connection time out.
+By consuming exceptions, the code will re-connect the socket in next loop iteration.
+
+```php
+$client = new WebSocket\Client("ws://echo.websocket.org/");
+while (true) {
+    try {
+        $message = $client->receive();
+        // Act on received message
+        // Break while loop to stop listening
+    } catch (\WebSocket\ConnectionException $e) {
+        // Possibly log errors
+    }
+}
+$client->close();
+```
+
+### Filtering received messages
+
+By default the `receive()` method return messages of 'text' and 'binary' opcode.
+The filter option allows you to specify which message types to return.
+
+```php
+$client = new WebSocket\Client("ws://echo.websocket.org/", ['filter' => ['text']]);
+$client->receive(); // Only return 'text' messages
+
+$client = new WebSocket\Client("ws://echo.websocket.org/", ['filter' => ['text', 'binary', 'ping', 'pong', 'close']]);
+$client->receive(); // Return all messages
+```
+
+### Sending messages
+
+There are convenience methods to send messages with different opcodes.
+```php
+$client = new WebSocket\Client("ws://echo.websocket.org/");
+
+// Convenience methods
+$client->text('A plain text message'); // Send an opcode=text message
+$client->binary($binary_string); // Send an opcode=binary message
+$client->ping(); // Send an opcode=ping frame
+$client->pong(); // Send an unsolicited opcode=pong frame
+
+// Generic send method
+$client->send($payload); // Sent as masked opcode=text
+$client->send($payload, 'binary'); // Sent as masked opcode=binary
+$client->send($payload, 'binary', false); // Sent as unmasked opcode=binary
+```
+
+## Constructor options
+
+The `$options` parameter in constructor accepts an associative array of options.
+
+* `context` - A stream context created using [stream_context_create](https://www.php.net/manual/en/function.stream-context-create).
+* `filter` - Array of opcodes to return on receive, default `['text', 'binary']`
+* `fragment_size` - Maximum payload size. Default 4096 chars.
+* `headers` - Additional headers as associative array name => content.
+* `logger` - A [PSR-3](https://www.php-fig.org/psr/psr-3/) compatible logger.
+* `persistent` - Connection is re-used between requests until time out is reached. Default false.
+* `return_obj` - Return a [Message](Message.md) instance on receive, default false
+* `timeout` - Time out in seconds. Default 5 seconds.
+
+```php
+$context = stream_context_create();
+stream_context_set_option($context, 'ssl', 'verify_peer', false);
+stream_context_set_option($context, 'ssl', 'verify_peer_name', false);
+
+$client = new WebSocket\Client("ws://echo.websocket.org/", [
+    'context' => $context, // Attach stream context created above
+    'filter' => ['text', 'binary', 'ping'], // Specify message types for receive() to return
+    'headers' => [ // Additional headers, used to specify subprotocol
+        'Sec-WebSocket-Protocol' => 'soap',
+        'origin' => 'localhost',
+    ],
+    'logger' => $my_psr3_logger, // Attach a PSR3 compatible logger
+    'return_obj' => true, // Return Message instance rather than just text
+    'timeout' => 60, // 1 minute time out
+]);
+```
+
+## Exceptions
+
+* `WebSocket\BadOpcodeException` - Thrown if provided opcode is invalid.
+* `WebSocket\BadUriException` - Thrown if provided URI is invalid.
+* `WebSocket\ConnectionException` - Thrown on any socket I/O failure.
+* `WebSocket\TimeoutException` - Thrown when the socket experiences a time out.

+# Websocket: Examples
+
+Here are some examples on how to use the WebSocket library.
+
+##  Echo logger
+
+In dev environment (as in having run composer to include dev dependencies) you have
+access to a simple echo logger that print out information synchronously.
+
+This is usable for debugging. For production, use a proper logger.
+
+```php
+namespace WebSocket;
+
+$logger = new EchoLogger();
+
+$client = new Client('ws://echo.websocket.org/');
+$client->setLogger($logger);
+
+$server = new Server();
+$server->setLogger($logger);
+```
+
+An example of server output;
+```
+info     | Server listening to port 8000 []
+debug    | Wrote 129 of 129 bytes. []
+info     | Server connected to port 8000 []
+info     | Received 'text' message []
+debug    | Wrote 9 of 9 bytes. []
+info     | Sent 'text' message []
+debug    | Received 'close', status: 1000. []
+debug    | Wrote 32 of 32 bytes. []
+info     | Sent 'close' message []
+info     | Received 'close' message []
+```
+
+## The `send` client
+
+Source: [examples/send.php](../examples/send.php)
+
+A simple, single send/receive client.
+
+Example use:
+```
+php examples/send.php --opcode text "A text message" // Send a text message to localhost
+php examples/send.php --opcode ping "ping it" // Send a ping message to localhost
+php examples/send.php --uri ws://echo.websocket.org "A text message" // Send a text message to echo.websocket.org
+php examples/send.php --opcode text --debug "A text message" // Use runtime debugging
+```
+
+## The `echoserver` server
+
+Source: [examples/echoserver.php](../examples/echoserver.php)
+
+A simple server that responds to recevied commands.
+
+Example use:
+```
+php examples/echoserver.php // Run with default settings
+php examples/echoserver.php --port 8080 // Listen on port 8080
+php examples/echoserver.php --debug //  Use runtime debugging
+```
+
+These strings can be sent as message to trigger server to perform actions;
+* `exit` - Server will initiate close procedure
+* `ping` - Server will send a ping message
+* `headers` - Server will respond with all headers provided by client
+* `auth` -  Server will respond with auth header if provided by client
+* For other sent strings, server will respond with the same strings
+
+## The `random` client
+
+Source: [examples/random_client.php](../examples/random_client.php)
+
+The random client will use random options and continuously send/receive random messages.
+
+Example use:
+```
+php examples/random_client.php --uri ws://echo.websocket.org // Connect to echo.websocket.org
+php examples/random_client.php --timeout 5 --fragment_size 16 // Specify settings
+php examples/random_client.php --debug //  Use runtime debugging
+```
+
+## The `random` server
+
+Source: [examples/random_server.php](../examples/random_server.php)
+
+The random server will use random options and continuously send/receive random messages.
+
+Example use:
+```
+php examples/random_server.php --port 8080 // // Listen on port 8080
+php examples/random_server.php --timeout 5 --fragment_size 16 // Specify settings
+php examples/random_server.php --debug //  Use runtime debugging
+```

+# Websocket: Messages
+
+If option `return_obj` is set to `true` on [client](Client.md) or [server](Server.md),
+the `receive()` method will return a Message instance instead of a string.
+
+Available classes correspond to opcode;
+* WebSocket\Message\Text
+* WebSocket\Message\Binary
+* WebSocket\Message\Ping
+* WebSocket\Message\Pong
+* WebSocket\Message\Close
+
+Additionally;
+* WebSocket\Message\Message - abstract base class for all messages above
+* WebSocket\Message\Factory - Factory class to create Msssage instances
+
+##  Message abstract class synopsis
+
+```php
+WebSocket\Message\Message {
+
+    public __construct(string $payload = '')
+    public __toString() : string
+
+    public getOpcode() : string
+    public getLength() : int
+    public getTimestamp() : DateTime
+    public getContent() : string
+    public setContent(string $payload = '') : void
+    public hasContent() : bool
+}
+```
+
+##  Factory class synopsis
+
+```php
+WebSocket\Message\Factory {
+
+    public create(string $opcode, string $payload = '') : Message
+}
+```
+
+## Example
+
+Receving a Message and echo some methods.
+
+```php
+$client = new WebSocket\Client('ws://echo.websocket.org/', ['return_obj' => true]);
+$client->text('Hello WebSocket.org!');
+// Echo return same message as sent
+$message = $client->receive();
+echo $message->getOpcode(); // -> "text"
+echo $message->getLength(); // -> 20
+echo $message->getContent(); // -> "Hello WebSocket.org!"
+echo $message->hasContent(); // -> true
+echo $message->getTimestamp()->format('H:i:s'); // -> 19:37:18
+$client->close();
+```

+# Websocket: Server
+
+The library contains a rudimentary single stream/single thread server.
+It internally supports Upgrade handshake and implicit close and ping/pong operations.
+
+Note that it does **not** support threading or automatic association ot continuous client requests.
+If you require this kind of server behavior, you need to build it on top of provided server implementation.
+
+##  Class synopsis
+
+```php
+WebSocket\Server {
+
+    public __construct(array $options = [])
+    public __destruct()
+    public __toString() : string
+
+    public accept() : bool
+    public text(string $payload) : void
+    public binary(string $payload) : void
+    public ping(string $payload = '') : void
+    public pong(string $payload = '') : void
+    public send(mixed $payload, string $opcode = 'text', bool $masked = true) : void
+    public receive() : mixed
+    public close(int $status = 1000, mixed $message = 'ttfn') : mixed
+
+    public getPort() : int
+    public getPath() : string
+    public getRequest() : array
+    public getHeader(string $header_name) : string|null
+
+    public getName() : string|null
+    public getPier() : string|null
+    public getLastOpcode() : string
+    public getCloseStatus() : int
+    public isConnected() : bool
+    public setTimeout(int $seconds) : void
+    public setFragmentSize(int $fragment_size) : self
+    public getFragmentSize() : int
+    public setLogger(Psr\Log\LoggerInterface $logger = null) : void
+}
+```
+
+## Examples
+
+### Simple receive-send operation
+
+This example reads a single message from a client, and respond with the same message.
+
+```php
+$server = new WebSocket\Server();
+$server->accept();
+$message = $server->receive();
+$server->text($message);
+$server->close();
+```
+
+### Listening to clients
+
+To continuously listen to incoming messages, you need to put the receive operation within a loop.
+Note that these functions **always** throw exception on any failure, including recoverable failures such as connection time out.
+By consuming exceptions, the code will re-connect the socket in next loop iteration.
+
+```php
+$server = new WebSocket\Server();
+while ($server->accept()) {
+    try {
+        $message = $server->receive();
+        // Act on received message
+        // Break while loop to stop listening
+    } catch (\WebSocket\ConnectionException $e) {
+        // Possibly log errors
+    }
+}
+$server->close();
+```
+
+### Filtering received messages
+
+By default the `receive()` method return messages of 'text' and 'binary' opcode.
+The filter option allows you to specify which message types to return.
+
+```php
+$server = new WebSocket\Server(['filter' => ['text']]);
+$server->receive(); // only return 'text' messages
+
+$server = new WebSocket\Server(['filter' => ['text', 'binary', 'ping', 'pong', 'close']]);
+$server->receive(); // return all messages
+```
+
+### Sending messages
+
+There are convenience methods to send messages with different opcodes.
+```php
+$server = new WebSocket\Server();
+
+// Convenience methods
+$server->text('A plain text message'); // Send an opcode=text message
+$server->binary($binary_string); // Send an opcode=binary message
+$server->ping(); // Send an opcode=ping frame
+$server->pong(); // Send an unsolicited opcode=pong frame
+
+// Generic send method
+$server->send($payload); // Sent as masked opcode=text
+$server->send($payload, 'binary'); // Sent as masked opcode=binary
+$server->send($payload, 'binary', false); // Sent as unmasked opcode=binary
+```
+
+## Constructor options
+
+The `$options` parameter in constructor accepts an associative array of options.
+
+* `filter` - Array of opcodes to return on receive, default `['text', 'binary']`
+* `fragment_size` - Maximum payload size. Default 4096 chars.
+* `logger` - A [PSR-3](https://www.php-fig.org/psr/psr-3/) compatible logger.
+* `port` - The server port to listen to. Default 8000.
+* `return_obj` - Return a [Message](Message.md) instance on receive, default false
+* `timeout` - Time out in seconds. Default 5 seconds.
+
+```php
+$server = new WebSocket\Server([
+    'filter' => ['text', 'binary', 'ping'], // Specify message types for receive() to return
+    'logger' => $my_psr3_logger, // Attach a PSR3 compatible logger
+    'port' => 9000, // Listening port
+    'return_obj' => true, // Return Message insatnce rather than just text
+    'timeout' => 60, // 1 minute time out
+]);
+```
+
+## Exceptions
+
+* `WebSocket\BadOpcodeException` - Thrown if provided opcode is invalid.
+* `WebSocket\ConnectionException` - Thrown on any socket I/O failure.
+* `WebSocket\TimeoutException` - Thrown when the socket experiences a time out.

+# Testing
+
+Unit tests with [PHPUnit](https://phpunit.readthedocs.io/).
+
+
+## How to run
+
+To run all test, run in console.
+
+```
+make test
+```
+
+
+## Continuous integration
+
+GitHub Actions are run on PHP versions
+`7.2`, `7.3`, `7.4` and `8.0`.
+
+Code coverage by [Coveralls](https://coveralls.io/github/Textalk/websocket-php).
+
+
+## Test strategy
+
+Test set up overloads various stream and socket functions,
+and use "scripts" to define and mock input/output of these functions.
+
+This set up negates the dependency on running servers,
+and allow testing various errors that might occur.
