PHP socket communication for UDP communication Example _php tutorial

Example of UDP communication for socket communication in PHP

This paper describes the UDP communication method of socket communication in PHP. Share to everyone for your reference. Specific as follows:

1. Create a simple UDP server

?

18//Server information

$server = ' udp://127.0.0.1:9998 ';

Message End Symbol

$msg _eof = "\ n";

$socket = Stream_socket_server ($server, $errno, $errstr, Stream_server_bind);

if (! $socket) {

Die ("$errstr ($errno)");

}

do {

Receiving information from the client

$INMSG = Stream_socket_recvfrom ($socket, 1024x768, 0, $peer);

Print out relevant information on the service side

echo "Client: $peer \ n";

echo "Receive: {$INMSG}";

Send a message to the client

$OUTMSG = substr ($INMSG, 0, (Strrpos ($INMSG, $msg _eof)). '--'. Date ("D M J h:i:s y\r\n");

Stream_socket_sendto ($socket, $OUTMSG, 0, $peer);

} while ($INMSG!== false);

2. Simple Client

?

12function udpget ($sendMsg = ", $ip = ' 127.0.0.1 ', $port = ' 9998 ') {

$handle = Stream_socket_client ("udp://{$ip}:{$port}", $errno, $ERRSTR);

if (! $handle) {

Die ("ERROR: {$errno}-{$errstr}\n");

}

Fwrite ($handle, $SENDMSG. " \ n ");

$result = Fread ($handle, 1024);

Fclose ($handle);

return $result;

}

$result = Udpget (' Hello world ');

echo $result;
