I'd try something like the code below,
or see if pear has a http class that returns the headers to you.

code:

if ($fh = fsockopen($ip_of_host); //could get ip via nslookup)

{

   fwrite($fh,"GET /somePath/someFile HTTP/1.0\r\n");

   fwrite($fh,"Host: [url=http://www.domain.com\r\n");]www.domain.com\r\n");[/url] 

   fwrite($fh,"\r\n");

   $strRes = fread($fh,2048);

   $strHeaders = substr($strRes,0,strpos("\r\n\r\n",$strRes));

   $arrHeaders = explode("\r\n,$strHeaders);

   $arrAscHeaders = array();

   foreach ($arrHeaders as $straHeader)

   {

      $arrAscHeaders[substr($straHeader,0,strpos(':',$straHeader)] = substr($straHeader,strpos(':',$straHeader) + 2);

   }

  print $arrAscHeaders['last-modified']; //look up in http rfc

}
