Status: Open
Bug Type: COM related
Operating system: Windows NT 4.0 SP 6
PHP Version: 4.0.6
Description: Getting values by reference don't work
I think it's very simple.
The COM-Object that I use is compiled with
Microsoft Visual C++ 6.0, if it matters.
The definition looks like this:
interface ICObject: IDispatch
{
[id(1), helpstring("Methode Init")]
HRESULT Init(BSTR bstrUser,
long lwinID,
BSTR bstrCustomer);
[id(2), helpstring("Methode CheckLogin")]
HRESULT CheckLogin(BSTR bstrUser,
BSTR bstrServer,
long *laccess);
[id(3), helpstring("Methode CloseData")]
HRESULT CloseData();
};
Note, that there is no VARIANT Type!
It's only BSTR and LONG.
So I get always a type mismatch, when I try to pass
variables with
$var = new VARIANT(8, VT_I4|VT_BYREF);
or
$var = new VARIANT("test", VT_BSTR);
It doesn't matter, if it's passed by reference or not.
I think it's a more general problem. PHP tries to pass
the values as type VARIANT, but the interface is of another
type (here BSTR or LONG). Of course, I could be wrong.
When I pass the values directly as PHP-variables, then I
don't get the type-mismatch warning, but the variables
passed by reference don't change, as you can see in the
first message.
I hope, I maked it clear.

type mismatch means, that your com object expects another type. as you see the error
message is german so the error doesn't happen in php but in the com-marshaller. you
have to check what type your object expects and change the VT_I4 to the corresponding
value.
if you can provide me an other example so that i can reproduce this on my machine i
could help you more detailed

It didn't work!
I get this:
Warning: Invoke() failed: Typ paßt nicht.
in D:wwwwebzeapplicationindex.php on line 10
translated: ...: Type mismatch.
Line 10 looks like this:
$instance->CheckLogin($user, COM_REMOTE_SERVER, $allowed);
I have tried all of the combinations I could think of,
VT_UI1|BYREF, VT_UI2|BYREF, VT_UI4|BYREF, VT_I1|BYREF,
VT_I2|BYREF, VT_I4|BYREF, VT_INT|BYREF, VT_UINT|BYREF
It doesn't matter. I get always the same type mismatch warning.
Note that the variable $allowed in the function of the
COM-Object is defined as "long".
Please help me to get this working.

$user = "test_user";
$allowed = new VARIANT(8, VT_I4|VT_BYREF);
$instance = new COM("dll.CObject") or die("Unable to
instanciate dll.CObject");
$instance->CheckLogin($user, COM_REMOTE_SERVER, $allowed);
echo $allowed->value;
/* you can use $allowed->type to check it against
* VT_* constants
* look into the php documentation for more flags
* passing variables by reference is a deprecated
* zend feature (i don't know why) and it didn't work
* in every case in earlier versions.
