A bare-bones PHP-based IRC client library built on React.
The recommended method of installation is through composer.
composer require phergie/phergie-irc-client-react
This example makes the bot greet other users as they join any of the channels in which the bot is present.
<?php
$connection = new \Phergie\Irc\Connection();
// ...
$client = new \Phergie\Irc\Client\React\Client();
$client->on('irc.received', function($message, $write, $connection, $logger) {
if ($message['command'] !== 'JOIN') {
return;
}
$channel = $message['params']['channels'];
$nick = $message['nick'];
$write->ircPrivmsg($channel, 'Welcome ' . $nick . '!');
});
$client->run($connection);
// Also works:
// $client->run(array($connection1, ..., $connectionN));
// Also possible:
// Don't autorun the event loopin case you pass your own event loop and run it yourself
// $client->run($connection, false);
\Phergie\Irc\Connection
, for each server the bot will connect to. See phergie-irc-connection documentation for more information on configuring connection objects.\Phergie\Irc\Client\React\Client
.on()
method any number of times, each time specifying an event to monitor and a callback that will be executed whenever that event is received from the server.run()
method with a connection object or array of multiple connection objects created in step #1.Below are the events supported by the client. Its on()
method can be used to add callbacks for them.
Emitted before any connections are established.
\Phergie\Irc\ConnectionInterface[] $connections
- array of all connection objects<?php
$client->on('connect.before.all', function(array $connections) {
// ...
});
Emitted after all connections are established.
\Phergie\Irc\ConnectionInterface[] $connections
- array of all connection objects\Phergie\Irc\Client\React\WriteStream[] $writes
- corresponding array of connection write streamsNote that if a connection attempt failed, the value in $writes
for that connection will be null
.
<?php
$client->on('connect.after.all', function(array $connections, array $writes) {
// ...
});
Emitted before each connection is established.
\Phergie\Irc\ConnectionInterface $connection
- object for the connection to be established<?php
$client->on('connect.before.each', function(\Phergie\Irc\ConnectionInterface $connection) {
// ...
});
Emitted after each connection is established.
One potentially useful application of this is to institute a delay between connections in cases where the client is attempting to establish multiple connections to the same server and that server throttles connection attempts by origin to prevent abuse, DDoS attacks, etc.
\Phergie\Irc\ConnectionInterface $connection
- object for the established connection\Phergie\Irc\Client\React\WriteStream|null $write
- write stream for the connectionNote that if the connection attempt failed, $write
will be null
.
<?php
$client->on('connect.after.each', function(\Phergie\Irc\ConnectionInterface $connection, \Phergie\Irc\Client\React\WriteStream $write) {
// ...
});
Emitted when an error is encountered on a connection.
Exception $exception
- exception describing the error that encountered\Phergie\Irc\ConnectionInterface $connection
- container that stores metadata for the connection on which the event occurred and implements the interface \Phergie\Irc\ConnectionInterface
(see its source code for a list of available methods)\Psr\Log\LoggerInterface $logger
- logger for logging any relevant events from the listener which go to stdout by default (see the Monolog documentation for more information)<?php
$client->on('connect.error', function(
\Exception $message,
\Phergie\Irc\ConnectionInterface $connection,
\Psr\Log\LoggerInterface $logger
) use ($client) {
$logger->debug('Connection to ' . $connection->getServerHostname() . ' lost: ' . $e->getMessage());
});
Emitted when a connection is terminated.
This can be useful for re-establishing a connection if it is unexpectedly terminated.
\Phergie\Irc\ConnectionInterface $connection
- container that stores metadata for the connection that was terminated and implements the interface \Phergie\Irc\ConnectionInterface
(see its source code for a list of available methods)\Psr\Log\LoggerInterface $logger
- logger for logging any relevant events from the listener which go to stdout by default (see the Monolog documentation for more information)<?php
$client->on('connect.end', function(\Phergie\Irc\ConnectionInterface $connection, \Psr\Log\LoggerInterface $logger) use ($client) {
$logger->debug('Connection to ' . $connection->getServerHostname() . ' lost, attempting to reconnect');
$client->addConnection($connection);
});
Emitted when an IRC event is received from the server.
array $message
- associative array containing data for the event received from the server as obtained by \Phergie\Irc\Parser
(see its documentation for examples)\Phergie\Irc\Client\React\WriteStream $write
- stream that will send new events from the client to the server when its methods are called and implements the interface \Phergie\Irc\GeneratorInterface
(see its source code for a list of available methods)\Phergie\Irc\ConnectionInterface $connection
- container that stores metadata for the connection on which the event occurred and implements the interface \Phergie\Irc\ConnectionInterface
(see its source code for a list of available methods)\Psr\Log\LoggerInterface $logger
- logger for logging any relevant events from the listener which go to stdout by default (see the Monolog documentation for more information)<?php
$client->on('irc.received', function(
array $message,
\Phergie\Irc\Client\React\WriteStream $write,
\Phergie\Irc\ConnectionInterface $connection,
\Psr\Log\LoggerInterface $logger
) {
// ...
});
Emitted when an IRC event is sent by the client to the server.
string $message
- message being sent by the client\Phergie\Irc\Client\React\WriteStream $write
- stream that will send new events from the client to the server when its methods are called and implements the interface \Phergie\Irc\GeneratorInterface
(see its source code for a list of available methods)\Phergie\Irc\ConnectionInterface $connection
- container that stores metadata for the connection on which the event occurred and implements the interface \Phergie\Irc\ConnectionInterface
(see its source code for a list of available methods)\Psr\Log\LoggerInterface $logger
- logger for logging any relevant events from the listener which go to stdout by default (see the Monolog documentation for more information)<?php
$client->on('irc.sent', function(
$message,
\Phergie\Irc\Client\React\WriteStream $write,
\Phergie\Irc\ConnectionInterface $connection,
\Psr\Log\LoggerInterface $logger
) {
// ...
});
Emitted periodically on each connection to allow events to be sent
asynchronously versus in response to received or sent events. The interval
between invocations is specified in seconds and set using the client's
setTickInterval()
method.
\Phergie\Irc\Client\React\WriteStream $write
- stream that will send new events from the client to the server when its methods are called and implements the interface \Phergie\Irc\GeneratorInterface
(see its source code for a list of available methods)\Phergie\Irc\ConnectionInterface $connection
- container that stores metadata for the connection on which the event occurred and implements the interface \Phergie\Irc\ConnectionInterface
(see its source code for a list of available methods)\Psr\Log\LoggerInterface $logger
- logger for logging any relevant events from the listener which go to stdout by default (see the Monolog documentation for more information)<?php
$client->on('irc.tick', function(
\Phergie\Irc\Client\React\WriteStream $write,
\Phergie\Irc\ConnectionInterface $connection,
\Psr\Log\LoggerInterface $logger
) {
// ...
});
In some cases, it's desirable to execute a callback on a specified interval rather than in response to a specific event.
To add one-time callbacks that execute after a specified amount of time (in seconds):
<?php
$client->addTimer(5, function() {
// ...
});
The above example will execute the specified callback at least 5 seconds after it's added.
To add recurring callbacks that execute on a specified interval (in seconds):
<?php
$client->addPeriodicTimer(5, function() {
// ...
});
The above example will execute the specified callback at least every 5 seconds after it's added.
Connection sockets will use IPv6 by default where available. If you need to force usage of IPv4, set this option to true
.
<?php
$connection->setOption('force-ipv4', true);
By default all ssl connections only accept officially signed certificates. Sometimes you need to connect to a irc server that uses a self signed certificate. If you need to allow connections to servers using a self signed certificate, set this option to true
.
<?php
$connection->setOption('allow-self-signed', true);
By default, a standard TCP socket is used. For IRC servers that support TLS or SSL, specify an appropriate transport.
<?php
$connection->setOption('transport', 'ssl');
