One could ask if it would just pass to the constructor, but it doesn't. I don't know if there's a technical reason for that or if just no one implemented it, but the short answer is "The language doesn't do that." (What may be confusing you is __toString(), which only works for *reading* if you *already have an object* and then use it in a string context. You don't already have an object and are trying to *write*, so the __toString() does nothing.) -- Larry Garfield AIM: LOLG42 [EMAIL PROTECTED] ICQ: 6817012 "If nature has made any one thing less susceptible than all others of exclusive property, it is the action of the thinking power called an idea, which an individual may exclusively possess as long as he keeps it to himself; but the moment it is divulged, it forces itself into the possession of every one, and the receiver cannot dispossess himself of it." -- Thomas Jefferson -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
