Re: [PHP-DEV] try..catch From: Andi Gutmans (andi <email protected>)

I agree that exceptions need to have their own scope. The last thing try {}
catch should encourage, and you can read this in any OOP book if it's C++
or Java, is to start implementing logic with/inside it instead of just
error recovery.
In the case of PHP, it will probably just want to print a nice error
messsage, maybe log the error message and terminate.
