README
Hoa is a modular, extensible and
structured set of PHP libraries.
Moreover, Hoa aims at being a bridge between industrial and research worlds.
Hoa\Eventsource
This library allows to manipulate the EventSource (aka Server-Sent Events) technology by creating a server.
Installation
With Composer, to include this library into
your dependencies, you need to
require hoa/eventsource
:
$ composer require hoa/eventsource '~3.0'
For more installation procedures, please read the Source page.
Testing
Before running the test suites, the development dependencies must be installed:
$ composer install
Then, to run all the test suites:
$ vendor/bin/hoa test:run
For more information, please read the contributor guide.
Quick usage
We propose as a quick overview to send an unlimited number of events from the
server to the client. The client will display all received events. Thus, in
Server.php
:
$server = new Hoa\Eventsource\Server(); while (true) { // “tick” is the event name. $server->tick->send(time()); sleep(1); }
And in index.html
, our client:
<pre id="output"></pre> <script> var output = document.getElementById('output'); try { var source = new EventSource('Server.php'); source.onopen = function () { output.appendChild(document.createElement('hr')); return; }; source.addEventListener('tick', function (evt) { var samp = document.createElement('samp'); samp.innerHTML = evt.data + '\n'; output.appendChild(samp); return; }); } catch (e) { console.log(e); } </script>
Start your HTTP server and then open index.html
.
The Hoa\Eventsource\Server::setReconnectionTime
method allows to redefine the
time before the client will reconnect after a disconnection. The
Hoa\Eventsource\Server::getLastId
method allows to retrieve the last ID sent
to the client.
