可能重复：
PHP 和 HTML：socket_connect() [function.socket-connect]：无法连接

我正在使用 PHP 连接到运行 Java .jar 的服务器。我安装了一个插件，允许来自外部 PHP 文件的连接。我不断收到连接超时错误。昨晚还好好的，不知道有什么变化。端口 4445 被转发，我可以通过 telnet 连接到它，并且我允许我的网站的 IP 在我的服务器的防火墙中。

您可以在此处查看 PHP 代码：http: //pastebin.com/PLAfApdT

<?php
 $HOST = "207.210.254.141"; //the ip of the bukkit server
 $password = "examplepassword1";
 $player = $_POST["fname"];
 if (empty($player)) {
     sleep(0);
     printf("<script language = 'javascript'>history.go(-1)</script>");}
 else {
 //Can't touch this:
 fsockopen($HOST, 4445)
 or die("error: could not connect to host\n");
 //Authentification
 fwrite($command = md5($password)."<Password>", strlen($command) + 1)
 or die("error: failed to write to socket\n");
 //Begin custom code here.
 fwrite($command = "/Command/ExecuteConsoleCommand:give $player 264 5;", strlen($command) + 1)
 or die("error: failed to write to socket\n");
 fwrite($command = "/Command/ExecuteConsoleCommand:say $player voted for MOOcraft and earned 5 diamonds. Vote at moocraft.org;", strlen($command) + 1)
 or die("error: failed to write to socket\n");
 echo "Thanks for Voting! You can vote again in 24 hours and recieve more diamonds!";}
?>
