ifx.php - getListOf('databases')

Hi all, I was looking at how to implement this function, and hit a snag. In common, getListOf() calls getSpecialQuery(), which may return either an SQL string, or a result set. In Informix, I need to call sqgetdbs() in ifx.ec, which returns a list of C strings. This would be called from ifx.php ... but, how can ifx.php return this list looking like a result set? Should it construct a result object to simulate the expected behaviour? Or is a change in common called for? (E.g. allowing getSpecialQuery to return an array as a third option) Any thoughts/suggestions appreciated. Kind regards, Peter
