Thanks, -KJW Proverbs 3:5-6 Since nobody else has offered anything, I'll give you my impression of how a try handles things. If the statement(s) within the try block fail in any way (such as simply returning a 'false' value), the try block's catch will be executed. So while the items you specified do not throw an exception, I believe the try will still handle a failure of those functions. Of course, if I'm wrong, I'm positive we'll start seeing responses to your question. :) -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

But how do/can you determine if false is a failure? /Lars -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

If the original function returned false then the try should catch it and in your 'catch' block you can display a message and show the php error. In the case where you expect a 'false' return, then just reverse your try condition, and display the appropriate message (without a php error messsage). Or even simpler, just use an If statement. -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
