ช่วยด้วยค่ะ PHP เขียนดึงข้อมูลจาก mysql ไปใส่ตารางใน access

<?php
require_once('Connections/conn.php'); 
$conn_string = "host=$host port=$port dbname=$db user=$user password=$pwd";
$dbConn = mysql_connect($conn_string);	

$filename = 'sql_export';
$delimiter = ',';
$endl = "\r\n";
 
$sql = "select * from persons";

$result = mysql_query($sql);   


if ( count($rowset) )
{
	header("Content-Type: application/x-msaccess");    
	header("Content-Disposition: attachment; filename=$filename.mdb"); 

      $line = '';
      
      foreach ( $rowset[0] as $column => $value )
      {
            $line .= $delimiter . $column;
      }
      echo substr($line, 1) . $endl;     
      
      for ($i = 0; $i < count($rowset); $i++)
      {
            $line = '';
            foreach ( $rowset[$i] as $value )
            {
                  $line .= $delimiter . $value;
            }
            echo substr($line, 1) . $endl;    
      }
}
else
{
      echo "<p>No data was exported</p>$endl";
}

?>
