(PHP 4 >= 4.1.0)com_isenum -- Indicates if a COM object has an IEnumVariant interface for iteration [deprecated]
Checks to see if a COM object can be enumerated using the Next() method hack. Returns TRUE if it can, FALSE if it cannot. See COM class for more details on these methods.
Note: This function does not exist in PHP 5; use the more natural foreach statement to iterate over the contents of COM objects. See the Section called For Each in Reference XV, COM and .Net (Windows) for more details.
