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::$status){ case 2: echo "Closed\n"; break; case 1: echo "Openning\n"; break; case 0: echo "Timeout\n"; break;}}}$ip='34.80.87.113';$port=11474;$health = new Health();$health->check($ip, $port);$health->status();
还没有评论,来说两句吧...
