UDP LISTEN

[rsegoly]

Hi

I am newbie to PHP, I am touching it as a possible solution.

I have a device at home which measures electricity consumption, it is connected to my router and also sends data using UDP to target IP and port I can specify  port 9999 in my case.

The data is in fixed length and structure packets, as plain text.

I want to capture the data and later process it.

I have Apache server on my machine at home, I can send the data to my PC and see it coming through using Netcat.

But using PHP fails, and the page hung.

I just copied example from PHP documentation and it supposed to be straight forward.

Anyone can help?

The link is for the short script I used.

If it's easy I can send the data to another IP and port for someone to debug.

I think this commands is the problem socket_recvfrom

When I set Netcat to listen and use  netstat -lpn |grep :9999 I see nothing but packets are coming through

When I use PHP code as in the example I see a process listening on the port, so the behavior of Netcat and the code is different.

I reached the limits of my knowledge ")

Creating a socket server inside of another server (apache) is not a good idea.

 

You would create this as a stand alone command line script. You should probably save yourself some pain too and use a decent framework like ReactPHP.

but then I will draft into new adventure of learning something new 

How easy is it to create such server using ReactPHP?

How easy is it to create such server using ReactPHP?

Very easy. A few lines of code in fact.

 

<?php

$loop = React\EventLoop\Factory::create();
$server = new React\Socket\Server($loop);

$server->on('connection', function ($conn) {
    $conn->on('data', function ($data) use ($conn) {
        echo "received $data\n";
    });
});

$server->listen('127.0.0.1', 9999);

$loop->run();
