I have the following code which tries to execute a stored procedure using ADODB created using COM. The ad Constants and strConnect have been defined in an include file.

$objCommand = new COM ("ADODB.Command");
$objCommand -> ActiveConnection = strConnect;
$objCommand -> CommandText = "someStoredProc";
$objCommand -> CommandType = adCmdStoredProc;

$objParam = $objCommand -> CreateParameter("strAction", adVarChar, adParamInput, 1);
$objCommand -> Parameters -> Append($objParam);
$objParam = $objCommand -> CreateParameter("intCategoryID", adInteger, adParamInput, 4);
$objCommand -> Parameters -> Append($objParam);
$objParam = $objCommand -> CreateParameter("strCategory", adVarChar, adParamInput, 100);
$objCommand -> Parameters -> Append($objParam);

$clnParameter = $objCommand -> Parameters;

echo gettype($clnParameter);

The display says $clnParameter is an object, while ADODB documentation says "Parameters" is a collection of Parameter object.
