Example Analysis of UDP Communication of Socket Communication in PHP

This article will explain in detail the example analysis of Socket communication in PHP. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

The details are as follows:

1. Create a simple UDP server

/ / 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 {/ / receive a message from the client $inMsg = stream_socket_recvfrom ($socket, 1024, 0, $peer) / / the server prints out relevant information echo "Client: $peer\ n"; echo "Receive: {$inMsg}"; / / sends 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)

two。 Simple client

Function 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; on "sample Analysis of UDP Communications in Socket Communications in PHP" this article ends here.
