passing an array to a COM object?

I'm getting an error when attempting to pass an array to a COM object as follows: ---------------------- Here's the PHP code: $myarray[0] = "zero"; $myarray[1] = "one"; $myarray[2] = "two"; $myarray[3] = "three"; echo $ref->Test($myarray); ---------------------- Here's the VB code: Public Function Test(strArray() As String) As String Test = strArray(1) End Function ----------------------- Here's the resulting error message: Warning: Invoke() failed: Type mismatch. in c:\inetpub\wwwroot\php-com.php on line 22 ----------------------- It works fine when try to pass in and return a simple non-array string. I know I'm doing something wrong on the PHP side of the fence....anyone know the answer?
