php 环境本地用ip连接mysql响应快，用localhost连接慢的解决

<?php
$address = gethostbyname ($ip);
        $command = "ping -c 1 " . $address; 
        $r = exec($command); 
          if ($r[0]=="r")
          {       
            $socket = socket_create (AF_INET, SOCK_STREAM, 0);
            if ($socket < 0) {
                echo "socket_create() failed: reason: " . socket_strerror ($socket) . "n";
            } else {
                echo "OK.n";
            }
?>
