## SYSTEM REQUIREMENTS
- PHP minimum 5.6 or minimum 7.0
- psr/log
- (optional) psr/log-implementation - like monolog/monolog for logging
## INSTALLATION
New to Composer? Read the [introduction](https://getcomposer.org/doc/00-intro.md#introduction). Add the following to your composer file:
```bash
composer require fabiang/xmpp
```
## DOCUMENTATION
This library uses an object to hold options:
```php
use Fabiang\Xmpp\Options;
$options = new Options($address);
$options->setUsername($username)
->setPassword($password);
```
The server address must be in the format `tcp://myjabber.com:5222`.
If the server supports TLS the connection will automatically be encrypted.
You can also pass a PSR-2-compatible object to the options object:
```php
$options->setLogger($logger)
```
The client manages the connection to the Jabber server and requires the options object:
```php
use Fabiang\Xmpp\Client;
$client = new Client($options);
// optional connect manually
$client->connect();
```
For sending data you just need to pass a object that implements `Fabiang\Xmpp\Protocol\ProtocolImplementationInterface`:
```php
use Fabiang\Xmpp\Protocol\Roster;
use Fabiang\Xmpp\Protocol\Presence;
use Fabiang\Xmpp\Protocol\Message;
// fetch roster list; users and their groups
$client->send(new Roster);
// set status to online
$client->send(new Presence);
// send a message to another user
$message = new Message;
$message->setMessage('test')
->setTo('nickname@myjabber.com')
$client->send($message);
// join a channel
$channel = new Presence;
$channel->setTo('channelname@conference.myjabber.com')
->setPassword('channelpassword')
->setNickName('mynick');
$client->send($channel);
// send a message to the above channel
$message = new Message;
$message->setMessage('test')
->setTo('channelname@conference.myjabber.com')
->setType(Message::TYPE_GROUPCHAT);
$client->send($message);
```
After all you should disconnect:
```php
$client->disconnect();
```
## DEVELOPING
If you like this library and you want to contribute, make sure the unit-tests and integration tests are running.
Composer will help you to install the right version of PHPUnit and [Behat](http://behat.org/).
composer install
After that:
./vendor/bin/phpunit
./vendor/bin/behat
New features should always tested with Behat.
