请参见如果服务器是PHP的一个端口上侦听? [英] See if a server is listening on a port in PHP?
问题描述
在回答之前,请注意,我是完全新的PHP。我听说它是强大的。
Before answering, please note that I am completely new to PHP. I have heard it is powerful.
我试图做的是有我(的Apache 2)Web服务器上的页面,当用户点击网页上的按钮时,服务器会检查是否一个端口是在它自己的IP上运行了preSET端口每个按钮,我想用相同IP的多个按钮,但不同的端口被ping通。
What I'm trying to do is have a page on my (Apache 2) web server that when a user clicks a button on the page, the server will check if a port is running on it's own IP with a preset port for each button, I want multiple buttons with the same IP but different ports to be pinged.
例如:
-
按钮1(界面完全音频服务器)被点击,服务器ping 127.0.0.1:7777并告诉用户,如果它得到响应与否。
Button 1 (Terraria Server) is clicked, server pings 127.0.0.1:7777 and tells the user if it gets a response or not.
按钮2(我的世界服务器)被点击,服务器ping 127.0.0.1:25565并告诉用户等等等等。
Button 2 (Minecraft Server) is clicked, server pings 127.0.0.1:25565 and tells the user etc etc.
我已经安装了PHP和工作,我需要的是一些code:)
I already have PHP installed and working, all I need is some code :)
推荐答案
尝试端口上的连接,并返回结果:
Attempt a connection on the port and return the result:
<?php
function Connect($port) {
$serverConn = @stream_socket_client("tcp://127.0.0.1:$port", $errno, $errstr);
if ($errstr != '') {
return false;
}
fclose($serverConn);
return true;
}
if(isset($_POST['portTest'])){
switch ($_POST['portTest']){
case 'minecraft': $port= '25565';
break;
case 'Terraria': $port= '7777';
break;
default: exit;
}
if (Connect($port)){
echo "Server is running!";
}else{
echo "Server is down";
}
}
?>
<form method="POST">
<input type="submit" name="portTest" value="minecraft">
<input type="submit" name="portTest" value="Terraria">
</form>
