อยากทราบว่า PHP ใช้ OLEDB เรียกไฟล์ DBF ผ่านทาง IP ยังไงครับ?

<?
//require_once('adodb/adodb.inc.php');
$hostname="docsrv";
$username="root"; 
$password="1234"; 
$dbName="suggestion"; 


$url="http://docsrv/suggestion";

mysql_connect($hostname, $username, $password) or die("เกิดความผิดพลาด");
mysql_select_db("$dbName") or die("ไม่สามารถเปิดฐานข้อมูลได้");
mysql_query("SET CHARACTER SET tis620");

//session_start();
echo "<script language='JavaScript' type='text/javascript'>
var hostname='docsrv';
</script>";

//$dbf='E:\AppServ\www\Suggestion\DBF';
//$dbf='\\192.168.63.123\suggestion\DBF';
//$dbf='\\\\192.168.63.123\\suggestion$\\suggest';
//$dbf='J:';
$dbf = "Server.MapPath('\\192.168.63.123\suggestion$\suggest\frm_sug.DBF');";


if(is_dir($db)) 
	echo 'successfully';
		else 'can not access';

ini_set("display_errors","on");

	$conn = new COM("ADODB.Connection");

   try {
      $conn->Open('Provider=VFPOLEDB.1;Data Source='.$dbf.';Mode=ReadWrite;Password="";Collating Sequence=MACHINE;');

//		 $conn->Open('Provider=VFPOLEDB.1;DSN=suggest;Mode=ReadWrite;Password="";Collating Sequence=MACHINE;');

         if (!$conn) {
			 throw new Exception("Could not connect!");
        }
   }
   catch (Exception $e) {
      echo "Error (File:): ".$e->getMessage()."<br/>";
   }

if (!$conn)
  {exit("Connection Failed: ".$conn);}

?>
