PHP检测服务器TCP端口

        之前拿来检测远程服务器是否正常运行的,也是从哪里弄来的代码,直接放出来给大家了

<?php
//实现TCP端口检测
class Health {
public static $status;
public function __construct(){
}
public function check($ip, $port){
$sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
socket_set_nonblock($sock);
socket_connect($sock,$ip, $port);
socket_set_block($sock);
self::$status = socket_select($r = array($sock), $w = array($sock), $f = array($sock), 5);
return(self::$status);
}
public function checklist($lst){
}
public function status(){
switch(self::$status){
case 2:
echo "Closedn";
break;
case 1:
echo "Openningn";
break;
case 0:
echo "Timeoutn";
break;
}
}
}
$ip='34.80.87.113';
$port=11474;
$health = new Health();
$health->check($ip, $port);
$health->status();
