RE: Catchable fatal error: Object of class stdClass could not be converted to string in <filename> on line <line>

["Max Thayer" <mthayer@xxxxxxxxxxxxxxx>]

Edit: I've added usage example and a clearer explanation of the code
snippet.

Catchable fatal error: Object of class stdClass could not be converted
to string in <filename> on line <line>

************************************************************ *****

I can only find the change log for PHP 5.2 identifying this type of
error, nothing on how to fix it. I have updated PHP to 5.2.3 on Apache
2.2.x on a BSD Box 6.x If some one could explain to me what I am doing
wrong, and what I need to do to fix it that would be swell.

A point of note is that my $dbh is being created in my class constructor
as a private. The method that is calling the prepare and execute
statements is a public. I don't thing I'm trying to do anything new or
exotic, I don't think I'm trying to convert the object to a string, just
execute the query statement....

//code snip of public function insertUser()
$begin = $this->dbh->beginTransaction();

if (!$begin) throw new HWIException(ERR0023,23);

$outdc = "";

$outliid = "";

$prep_users = $this->dbh->prepare($sql_users);
if (!$prep_users) {
$msg = $this->dbh->errorInfo();
throw new HWIException(ERR0021 . " " . $msg[2], 21);
}
$prep_users->bindParam(':username', $this->userObj->hwi_username,
PDO::PARAM_STR, 16);

$prep_users->bindParam(':title', $this->userObj->hwi_title,
PDO::PARAM_STR, 4);

$prep_users->bindParam(':firstname', $this->userObj->hwi_firstname,
PDO::PARAM_STR, 30);

$prep_users->bindParam(':midinit', $this->userObj->hwi_midinit,
PDO::PARAM_STR, 1);

$prep_users->bindParam(':lastname', $this->userObj->hwi_lastname,
PDO::PARAM_STR, 45);

$prep_users->bindParam(':priphone', $this->userObj->hwi_priphone,
PDO::PARAM_STR, 30);

$prep_users->bindParam(':priext', $this->userObj->hwi_priext,
PDO::PARAM_STR, 10);

$prep_users->bindParam(':secphone', $this->userObj->hwi_secphone,
PDO::PARAM_STR, 30);

$prep_users->bindParam(':secext', $this->userObj->hwi_secext,
PDO::PARAM_STR, 10);

$prep_users->bindParam(':fax', $this->userObj->hwi_fax, PDO::PARAM_STR,
30);

$prep_users->bindParam(':isPI', $this->userObj->hwi_ispi,
PDO::PARAM_INT);

$prep_users->bindParam(':date_returned', $outdc, PDO::PARAM_STR);

$prep_users->bindParam(':liid', $outliid, PDO::PARAM_STR);

if(!$exec) {

USAGE
test.php
************************************************************ ****
$userobject->username = 'mysuername';
$userobject->lastname = 'mylastname';
// continue on w/ each property as described in the bindParam statements
in the insertUser() method.

//class MyUser extends PDO (I started out extending PDO, changed to code
to debug it by creating a $dbh object in the constructor, and switched
back to extending PDO. Nothing works.

$userObj = new MyUser($userObject);
$userObj->insertUser();
