把下面的代码另存为deamon.php后, 在服务器上用后台模式执行: php -f deamon.php &
然后在其它电脑上就可以使用telnet 127.0.0.1 10000 进行连接了。
<?php /* 设置不显示任何错误 */ error_reporting(0); /* 脚本超时为无限 */ set_time_limit(0); /* 本机的IP和需要开放的端口 */ $address = '127.0.0.1'; $port = 10000; /* 产生一个Socket */ if (($sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP)) < 0) { echo "socket_create() failed: reason: " . socket_strerror($sock) . "\n"; } /* 把IP地址端口进行绑定 */ if (($ret = socket_bind($sock, $address, $port)) < 0) { echo "socket_bind() failed: reason: " . socket_strerror($ret) . "\n"; } /* 监听Socket连接 */ if (($ret = socket_listen($sock, 5)) < 0) { echo "socket_listen() failed: reason: " . socket_strerror($ret) . "\n"; } /* 永远循环监接受用户连接 */ do { if (($msgsock = socket_accept($sock)) < 0) { echo "socket_accept() failed: reason: " . socket_strerror($msgsock) . "\n"; break; } /* 发送提示信息给连接上来的用户 */ $msg = "==========================================\r\n" . " Welcome to the PHP Server. \r\n\r\n". " To quit, type 'quit'. \r\n" . " To shut down the server type 'shutdown'.\r\n" . " To get help message type 'help'.\r\n" . "==========================================\r\n" . "php> "; socket_write($msgsock, $msg, strlen($msg)); do { if (false === ($buf = socket_read($msgsock, 2048, PHP_NORMAL_READ))) { echo "socket_read() failed: reason: " . socket_strerror($ret) . "\n"; break 2; } if (!$buf = trim($buf)) { continue; } /* 客户端输入quit命令时候关闭客户端连接 */ if ($buf == 'quit') { break; } /* 客户端输入shutdown命令时候服务端和客户端都关闭 */ if ($buf == 'shutdown') { socket_close($msgsock); break 2; } /* 客户端输入help命令时候输出帮助信息 */ if ($buf == 'help') { $msg = " PHP Server Help Message \r\n\r\n". " To quit, type 'quit'. \r\n" . " To shut down the server type 'shutdown'.\r\n" . " To get help message type 'help'.\r\n" . "php> "; socket_write($msgsock, $msg, strlen($msg)); continue; } /* 客户端输入命令不存在时提示信息 */ $talkback = "PHP: unknow command '$buf'.\r\nphp> "; socket_write($msgsock, $talkback, strlen($talkback)); echo "$buf\n"; } while (true); socket_close($msgsock); } while (true); /* 关闭Socket连接 */ socket_close($sock); ?>
