A php client for Nats Streaming Server.
Uses phpnats under the hood and closesly resembles it's api.
- php 5.6+
- stan
Get composer:
curl -O http://getcomposer.org/composer.phar && chmod +x composer.pharAdd php-nats-streaming as a dependency to your project
php composer.phar require 'byrnedo/php-nats-streaming:^0.2.4'$options = new \NatsStreaming\ConnectionOptions();
$options->setClientID("test");
$options->setClusterID("test-cluster");
$c = new \NatsStreaming\Connection($options);
$c->connect();
// Publish
$r = $c->publish('special.subject', 'some serialized payload...');
// optionally wait for the ack
$gotAck = $r->wait();
if (!$gotAck) {
...
}
$c->close();If publishing many messages at a time, you might at first do this:
foreach ($req as $data){
$r = $c->publish(...);
$gotAck = $r->wait();
if (!$gotAck) {
...
}
}It's actually much faster to do the following:
$rs = [];
foreach ($req as $data){
$rs[] = $c->publish(...);
}
foreach ($rs as $r){
$r->wait();
}$options = new \NatsStreaming\ConnectionOptions();
$c = new \NatsStreaming\Connection($options);
$c->connect();
$subOptions = new \NatsStreaming\SubscriptionOptions();
$subOptions->setStartAt(\NatsStreamingProtos\StartPosition::First());
$sub = $c->subscribe('special.subject', function ($message) {
// implement
}, $subOptions);
$sub->wait(1);
// not explicitly needed
$sub->unsubscribe(); // or $sub->close();
$c->close();If you want to subscribe to multiple channels you can use $c->wait():
...
$c->connect();
...
$sub = $c->subscribe('special.subject', function ($message) {
// implement
}, $subOptions);
$sub2 = $c->subscribe('special.subject', function ($message) {
// implement
}, $subOptions);
$c->wait();$options = new \NatsStreaming\ConnectionOptions();
$c = new \NatsStreaming\Connection($options);
$c->connect();
$subOptions = new \NatsStreaming\SubscriptionOptions();
$sub = $c->queueSubscribe('specialer.subject', 'workgroup', function ($message) {
// implement
}, $subOptions);
$sub->wait(1);
// not explicitly needed
$sub->close(); // or $sub->unsubscribe();
$c->close();$options = new \NatsStreaming\ConnectionOptions();
$c = new \NatsStreaming\Connection($options);
$c->connect();
$subOptions = new \NatsStreaming\SubscriptionOptions();
$subOptions->setManualAck(true);
$sub = $c->subscribe('special.subject', function ($message) {
$message->ack();
}, $subOptions);
$sub->wait(1);
