PHP utilizes Stream_socket_server and stream_socket_client

Above PHP for the server, it will listen for messages until pressed: Ctrl + C
while (true)
{
Execute once every 5 seconds
Receive_message (' 127.0.0.1 ', ' 85 ', 5);
}
Custom functions to get messages
function Receive_message ($ips tutorial erver, $portnumber, $nbsecondsidle)
{
Create a socket
$socket =stream_socket_server (' tcp://'. $ipserver. ': $portnumber, $errno, $ERRSTR);
if (! $socket)
{
If you create a socket failed output
echo "$errstr ($errno) <br/>n";
}
Else
{
Accept socket connection and get information if the creation succeeds
while ($conn = @stream_socket_accept ($socket, $nbsecondsidle))
{
$message =read ($conn, 1024);
Echo ' I have received that: '. $message;
Fputs ($conn, "okn");
Fclose ($conn);
}
Fclose ($socket);
}
}
Server End
?>
<?php
The following code is the client, which sends the message and reads the reply
Send_message (' 127.0.0.1 ', ' n ', ' message to send ... ');
Custom functions, sending information
function Send_message ($ipserver, $portserver, $message)
{
$FP =stream_socket_client ("tcp://$ipserver: $portserver", $errno, $ERRSTR);
if (! $fp)
{
echo "Erreur: $errno-$errstr <br/>n";
}
Else
{
Fwrite ($fp, "$messagen");
$response = Fread ($fp, 4);
if ($response!= "OKN")
{
echo ' command couldn ' t be executed...ncause: '. $response;
}
Else
{
echo ' execution successfull ... ';
}
Fclose ($FP);
}
}
