Script returns offline for every ping

I have the script below, and it can ping any IP statically put in the file, but when I post to it it always fails.

<?php
$server = $_POST['ip'];
if (!$socket = @fsockopen("$server", 80, $errno, $errstr))
{
  echo "<font color='red'><strong>Offline!</strong></font>";
}
else 
{
  echo "<font color='green'><strong>Online!/strong></font>";


  fclose($socket);
}

?>

I've added several functions:

<?php
function port($Host, $Port = '')
   {
   if (strstr($Host, ':'))
      {
      if (strstr($Host, '/'))
         {
         $Output = substr($Host, strpos($Host, ':') +1, (strpos($Host, '/') -1) - strpos($Host, ':'));
         }
      else
         {
         $Output = substr($Host, strpos($Host, ':') +1);
         }
      }

   if ((isset($Output)) and ($Output != ''))
      {
      return $Output;
      }
   else
      {
      if ($Port != '')
         {
         return $Port;
         }
      }
   }

function server($Host)
    {
   if (strpos($Host, '//'))
      {
      $Host = substr($Host, strpos($Host, '//') +2);
      }

   if(strstr($Host,"/"))
        {
        $Host = substr($Host, 0, strpos($Host, "/"));
        }

   if(strstr($Host,":"))
        {
        $Host = substr($Host, 0, strpos($Host, ":"));
        }

    return $Host;
    }

    $Host = $_GET['ip'];
    $Host = server($Host);

    $churl = @fsockopen($Host, 80, $errno, $errstr, 10);

if (!$churl) { 
    echo("<div><b>Offline</b></div>"); 
    } 
    else 
    { 
    echo("<div><b>Online</b></div>"); 
    }



?>
