A project of mine requires that I call a dll using php via a COM object call:

$obj = new COM("SimplAt1Com.SimpleObj") or die ( "Unable to instantiate the COM!");

This call seems to work ok but the moment I try to call a function from the object using:

$result = $obj->put_Name("A") ;

none of the code after this call gets run.

Can anyone shed some light on what could cause this?

Also if anyone has a or knows of a known good dll that has functions that can be called from php in this manner I would be very interested in it. That way I could at least verify my server is set up correctly for such an operation.

Thanks, ~AJ

Wrap this in a try..catch block so you can output the message of the exception and get more information on what's going wrong. I think the com object isn't registered on the server but have a look at the exception for more info.

try {
$obj = new COM("SimplAt1Com.SimpleObj") or die ( "Unable to instantiate the COM!");

$result = $obj->put_Name("A") ;

} catch (Exception $e) {
    echo 'Caught exception: ',  $e->getMessage(), "\n";

Good luck!

Thanks for the post.

I tried what you suggested...

I get the error:

Fatal error: Call to undefined method com::put_Name()

Do I have to 'define' method's?

If so, is it done in the dll code or in my php script??


I think I may have just answered my own question; I looked at the code more closely and the function I tried to call was 1.) in a class and 2.) the function that calls the class is a 'Private Sub'.

I think I read somewhere that they need to be 'Public' functions.

Does this sound right?
