I have a PHP file about MQTT publish. When I run this PHP file in the terminal it run properly and no error everything was fine, But when I open it via a browser I get an error like this:
Warning: stream_socket_client(): unable to connect to tcp://xxx.xxx.xxx.xxx:1883 (Permission denied) in /var/www/mydomain/html/PLC-controller/phpMQTT.php on line 148

Hello @wattanaipongtham ,
Check your php.ini settings for the parameter safe_mode. It should be Off. Also try to disable suhosin if it’s running.
If it’s not solved, tell me if you are using Apache or Nginx?
