I'm in the middle of a callback during an xmlrpc request and it's required to return a specifically structured array no matter what.

at 20:40 If you're writing new code, write it for PHP5. There is no try/catch (exception) in PHP4. –Till Apr 14 '09 at 13:19 1 Maybe you should upvote the answer if you think it's worth of being "the answer" –Patrick Cornelissen Mar 26 '10 at 12:06 add a comment| 1 Answer 1 active oldest votes up vote 2 down vote accepted Late answer, I realise, sorry. I hope this is still relevant for you: First, I'm echoing the comments your got in response to your post. PHP5 is the way to go. However: I'm in the middle of a callback during an xmlrpc request and it's required to return a specifically structured array no matter what. If you can vouch for that the program cannot possibly continue without getting a structured array back, and you absolutely have to work with PHP4, then an exit() or die() with detailed error information will get you much the same effect as a fatal exception would. That's far removed from being graceful, of course. If you want something catchable, then return values and if-checking the result are your best bet, unfortunately. There are some standard ways of passing back specific error objects, but it's still the same thing - return the error object, if-check whether the result was an error object, react. Still,

Here's the code I got. I resorted to this solution because apparently (hear-say) my solution with die() wouldn't work with COM objects. So happy with that solution, but how can I make the stuff below work with PHP4.x? PHP Code: //PHP5solution
