Extending PDO

Was trying to make a quick wrapper for PDO as an example and am having some issues with it seg faulting I am hoping I am doing something stupid.. Using newly compiled 5.1.0b3 cli mode PDO itself works fine, Its just when I try to extend it.

$dsn         = "mysql:dbname=123;host=localhost";
$dbuser          = "123";
$dbpass          = "123";

class PDO_Dynamic extends PDO {

       private $dsn;
       private $dbuser;
       private $dbpass;

       function PDO_Dynamic($dsn, $dbuser, $dbpass) {
           $this->dsn = $dsn;
           $this->dbuser = $dbuser;
           $this->dbpass = $dbpass;
           $temp = $this->PDO($dsn, $dbuser, $dbpass);

       }

} $db_read = new PDO_Dynamic($dsn, $dbuser, $dbpass); $db_write = new PDO_Dynamic($dsn, $dbuser, $dbpass.'-'); -- Richard Thomas - CEO Cyberlot Technologies Group Inc. 507.398.4124 - Voice
