PHP的Socket通信之UDP通信實例
PHP的Socket通信之UDP通信的方法，你懂嗎？以下是百分網(wǎng)小編分享給大家，供大家參考。
1.創(chuàng)建一簡單的UDP服務(wù)器
18/pic/p>
$server = 'udp:/pic/p>
/pic/p>
$msg_eof = "n";
$socket = stream_socket_server($server, $errno, $errstr, STREAM_SERVER_BIND);
if (!$socket) {
die("$errstr ($errno)");
}
do {
/pic/p>
$inMsg = stream_socket_recvfrom($socket, 1024, 0, $peer);
/pic/p>
echo "Client : $peern";
echo "Receive : {$inMsg}";
/pic/p>
$outMsg = substr($inMsg, 0, (strrpos($inMsg, $msg_eof))).' -- '.date("D M j H:i:s Yrn");
stream_socket_sendto($socket, $outMsg, 0, $peer);
} while ($inMsg !== false);
2.簡單的客戶端
?
12function udpGet($sendMsg = '', $ip = '127.0.0.1', $port = '9998'){
$handle = stream_socket_client("udp:/pic/p>
if( !$handle ){
die("ERROR: {$errno} - {$errstr}n");
}
fwrite($handle, $sendMsg."n");
$result = fread($handle, 1024);
fclose($handle);
return $result;
}
$result = udpGet('Hello World');
echo $result;
希望本文所述對大家的php程序設(shè)計有所幫助。
