accessing class variables in PHP

ckb

hi all.
one doubt/....

now i am using class in PHP for my pgms...

my class is

GetAll.inc.php

<?
class GetAll{
function GetRegion($num)
{
$query=mysql_query("select reg_id ,reg_name from cregion ORDER BY reg_name");

    echo"<select size=\"1\" name=\"RN\">";
    echo "<option >Choose a Region</option>";

    while($row = mysql_fetch_array($query))
    {
      $reg=$row[reg_id];

      echo "<option value=\"$reg\"";
      if ($reg == $num)
      echo " selected";
      echo ">$row[reg_name]</option>n";
    }
    echo "</select>";
   }

}
?>

i am making use of this class in another php file like this and i am getting result also...(ie. for populating dropdown box Region)

that part of code is this:

<tr>
<td width="158" height="22" align="right" class="officeBearers">Region</td>
<td width="5" height="22"> </td>
<td width="532" height="22">
<?php

    include("connect.inc.php");         
    $objmysqlcon= new Connect();
    $objmysqlcon->start_connectmysql();
    include("GetAll.inc.php");
    $post[0]=$_POST['RN'];
    $O=new GetAll();
    $O->GetRegion($post[0]);
    ?>
    </td>
    </tr>

Now i want to save a combination for making use for search later .....

    $search_strval  = Trim($vREGID).Trim($vESTNAME);
     $search_strval .= Trim($vCOMPUTERIZED_YR);


     $qrysearch_str= "update hos_computer SET hos_computer.search_str = '$search_strval' where ESTCD ='$vESTCD'";
     $searchresult_str=mysql_query($qrysearch_str)
                             or die("Error in query:$qrysearch_str.". mysql_error());

here

$vREGID=$_POST['RN']; which is from that class file.

i need to get the region name in place of this and form my serach_strval like

$search_strval = Trim($vREGIONNAME).Trim($vESTNAME);
$search_strval .= Trim($vCOMPUTERIZED_YR);

HOW TO GET THIS REGION NAME FROM THAT CLASS.....IN MY DROP DOWN PASSING VALUE IS REGIONID AND DISPLAYING VALUES IS REGIONNAME...SO I WANT THIS DISPLAYING VALUE TO BE IN SEARCH STRING....

pls help me
thanx
