我写的一个检测远程主机的类

<?

  $times=$H*$h+$M*$i+$S;
  if ($times-$time_s>=10)
  {

  }
  else
  {

   {

printf ("[页面执行时间: %.2f秒]\n\n",($time_end - $time_start));
#echo microtime();
?>


问题(由于网络原因,时儿能通过检查,时而不能通过,我想用时间不,控制时间,可是还是不行:可能是我程序的问题^_*)
还有就是,用fopen检测好像效率不高
希望高手们帮看看,要怎么才能达到那种效果
还是就有没有更有效率...

这玩意嘛用？

是想要做一个延时的检测远程主机是否存在
