Q on mqtt client lib

[ebolisa]

Hi,

The code below fails with error

Quote

Fatal error: Maximum execution time of 30 seconds exceeded in C:\Apache24\htdocs\mqtt\phpMQTT.php on line 289

and I just cannot understand what's causing the issue. So, I really appreciate some help.

TIA

 

<?php
require("phpMQTT.php");

$server = "server.com";     // change if necessary
$port = 1883;                     // change if necessary
$username = "";                   // set your username
$password = "";                   // set your password
$client_id = "MqttClient-client"; // make sure this is unique for connecting to sever - you could use uniqid()

$mqtt = new phpMQTT($server, $port, $client_id);

if(!$mqtt->connect(true,NULL,$username,$password)){
    echo "Connection error!";
  exit(1);
}
else {
    echo "Connected!";
    echo "<br>";
}

//currently subscribed topics
$topics["casa/rp2/soil/moist"] = array("qos"=>1, "function"=>"procmsg");
$mqtt->subscribe($topics, 1);

while($mqtt->proc()){
}
$mqtt->close();

function procmsg($topic,$msg){
  echo "Msg Recieved: $msg";
}

and lib's line 289 is

usleep(10000);

If you're running some kind of long-term process (and you expect it to run for a long time) then you need to disable the script timeout. That's to be expected. But you should consider whether you really want to be doing that for a script running through your web server.

I just want to read mqtt data when I'm refreshing the page. So, it's not a long term-process.

How does the loop you started with the call to proc() get stopped?
