Script returns offline for every ping
<p>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.</p>

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


  fclose($socket);
}

?&gt;
</code></pre>
