I have installed MQTT broker on my windows machine from https://mosquitto.org/download/.
I am using https://github.com/bluerhinos/phpMQTT/tree/master/examples for publish and subscribe. Publish works as expected but subscribe did not work.
I did not understand why this is not work. MQTT broker require for connect remote MQTT server ? I want to implement publish and subscribe method in php
Publish:
require("../phpMQTT.php");
$mqtt = new phpMQTT("host", 1883, "124464646464/32"); //Change client name to something unique
if ($mqtt->connect()) {
echo "Connect Sucssfully";
try
{
$mqtt->publish("124464646464/Test","Hello HK123! at ".date("r"),0);
echo "<br>publish done";
$mqtt->close();
}
catch(Exception $e)
{
echo $e;
}
}
Subscribe:
ini_set('output_buffering','on');
require("../phpMQTT.php");
$mqtt = new phpMQTT("host", 1883, "124464646464/27"); //Change client name to something unique
if(!$mqtt->connect()){
exit(1);
}
$topics['124464646464/Test'] = array("qos"=>0, "function"=>"procmsg");
$mqtt->subscribe($topics,0);
while($mqtt->proc()){
}
$mqtt->close();
function procmsg($topic,$msg){
echo "Msg Recieved: ".date("r")."\nTopic:{$topic}\n$msg\n";
}
Error: wrong subscribe header
Get error form host error log
Edit:
I have run subscribe script using command line and it's always print
"eof receive going to reconnect for good measure\n" means always get true from feof function
code:
if(feof($this->socket)){
if($this->debug) echo "eof receive going to reconnect for good measure\n";
fclose($this->socket);
$this->connect_auto(false);
if(count($this->topics))
$this->subscribe($this->topics);
}
I have tested my publish page using chrome extension means subscribe using chrome extension and it's working fine means something in wrong in read socket .
