This article describes the UDP communication method of PHP Socket communication. Share it with you for your reference. The details are as follows:

1. create a simple UDP server

?

18 // server information

$ Server = 'udp: // 127.0.0.1: 8080 ';

// Message end symbol

$ Msg_eof = "\ n ";

$ Socket = stream_socket_server ($ server, $ errno, $ errstr, STREAM_SERVER_BIND );

If (! $ Socket ){

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

}

Do {

// Receive information sent from the client

$ InMsg = stream_socket_recvfrom ($ socket, 1024, 0, $ peer );

// The server prints the relevant information

Echo "Client: $ peer \ n ";

Echo "Receive: {$ inMsg }";

// Send information 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

?

12 function udpGet ($ sendMsg = '', $ ip = '2017. 0.0.1 ', $ port = '20160301 '){

$ 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;
