Interfaces
- ServerInterface
- The `ServerInterface` is responsible for providing an interface for accepting incoming streaming connections, such as a normal TCP/IP connection.

- $server : mixed
Methods
- __construct() : mixed
- [Deprecated] `Server`
- close() : void
- Shuts down this listening socket
- emit() : mixed
- getAddress() : string|null
- Returns the full address (URI) this server is currently listening on
- listeners() : array<string|int, mixed>
- on() : mixed
- once() : mixed
- pause() : void
- Pauses accepting new incoming connections.
- removeAllListeners() : mixed
- removeListener() : mixed
- resume() : void
- Resumes accepting new incoming connections.

Methods
__construct()
[Deprecated] `Server`
public
__construct(string|int $uri[, LoopInterface $loop = null ][, array<string|int, mixed> $context = array() ]) : mixed
This class exists for BC reasons only and should not be used anymore.
// deprecated
$socket = new React\Socket\Server(0);
$socket = new React\Socket\Server('127.0.0.1:8000');
$socket = new React\Socket\Server('127.0.0.1:8000', null, $context);
$socket = new React\Socket\Server('127.0.0.1:8000', $loop, $context);
// new
$socket = new React\Socket\SocketServer('127.0.0.1:0');
$socket = new React\Socket\SocketServer('127.0.0.1:8000');
$socket = new React\Socket\SocketServer('127.0.0.1:8000', $context);
$socket = new React\Socket\SocketServer('127.0.0.1:8000', $context, $loop);
This class takes an optional LoopInterface|null $loop
parameter that can be used to
pass the event loop instance to use for this object. You can use a null
value
here in order to use the default loop.
This value SHOULD NOT be given unless you're sure you want to explicitly use a
given event loop instance.
For BC reasons, you can also pass the TCP socket context options as a simple
array without wrapping this in another array under the tcp
key.
Parameters
- $uri : string|int
- $loop : LoopInterface = null
- $context : array<string|int, mixed> = array()

close()
Shuts down this listening socket
public
close() : void
This will stop listening for new incoming connections on this socket.
Calling this method more than once on the same instance is a NO-OP.
emit()
public
emit(mixed $event[, array<string|int, mixed> $arguments = [] ]) : mixed
Parameters
- $event : mixed
- $arguments : array<string|int, mixed> = []
getAddress()
Returns the full address (URI) this server is currently listening on
public
getAddress() : string|null
$address = $socket->getAddress();
echo 'Server listening on ' . $address . PHP_EOL;
If the address can not be determined or is unknown at this time (such as
after the socket has been closed), it MAY return a NULL
value instead.
Otherwise, it will return the full address (URI) as a string value, such
as tcp://127.0.0.1:8080
, tcp://[::1]:80
or tls://127.0.0.1:443
.
Note that individual URI components are application specific and depend
on the underlying transport protocol.
If this is a TCP/IP based server and you only want the local port, you may use something like this:
$address = $socket->getAddress();
$port = parse_url($address, PHP_URL_PORT);
echo 'Server listening on port ' . $port . PHP_EOL;
Return values
string|null —the full listening address (URI) or NULL if it is unknown (not applicable to this server socket or already closed)
listeners()
public
listeners([mixed $event = null ]) : array<string|int, mixed>
Parameters
- $event : mixed = null
Return values
array<string|int, mixed>on()
public
on(mixed $event, callable $listener) : mixed
Parameters
- $event : mixed
- $listener : callable
once()
public
once(mixed $event, callable $listener) : mixed
Parameters
- $event : mixed
- $listener : callable
pause()
Pauses accepting new incoming connections.
public
pause() : void
Removes the socket resource from the EventLoop and thus stop accepting new connections. Note that the listening socket stays active and is not closed.
This means that new incoming connections will stay pending in the operating system backlog until its configurable backlog is filled. Once the backlog is filled, the operating system may reject further incoming connections until the backlog is drained again by resuming to accept new connections.
Once the server is paused, no futher connection
events SHOULD
be emitted.
$socket->pause();
$socket->on('connection', assertShouldNeverCalled());
This method is advisory-only, though generally not recommended, the
server MAY continue emitting connection
events.
Unless otherwise noted, a successfully opened server SHOULD NOT start in paused state.
You can continue processing events by calling resume()
again.
Note that both methods can be called any number of times, in particular
calling pause()
more than once SHOULD NOT have any effect.
Similarly, calling this after close()
is a NO-OP.
removeAllListeners()
public
removeAllListeners([mixed $event = null ]) : mixed
Parameters
- $event : mixed = null
removeListener()
public
removeListener(mixed $event, callable $listener) : mixed
Parameters
- $event : mixed
- $listener : callable
resume()
Resumes accepting new incoming connections.
public
resume() : void
Re-attach the socket resource to the EventLoop after a previous pause()
.
$socket->pause();
Loop::addTimer(1.0, function () use ($socket) {
$socket->resume();
});
Note that both methods can be called any number of times, in particular
calling resume()
without a prior pause()
SHOULD NOT have any effect.
Similarly, calling this after close()
is a NO-OP.
