[PHP] FormatDateTime in PHP

[Skyhawk]

Please, 

How do I make to format my date in the my format? For Example:

## I filter
$filter = " SELECT DTVECTO FROM CLIENTS";
$result = mysql_query($filter);
$rows   = mysql_num_rows($result);
while($rows = mysql_fetch_array($result)) {
   ## I get date to the data base 
   $my_date = $rows["DTVECTO"];
   ## I print
   print($my_date);
}

I want to show my date in format: 01/12/2003 (dd/mm/yyyy).
For Example
Date                Value
01/09/2003     $ 50.00
01/10/2003     $ 60.00
01/11/2003     $ 70.00



thanks
