If you were to enable xdebug, I am sure it could give you some insight. As could switching all errors to exceptions temporarily, maybe. A white screen often has the root cause suppressed by error_level, executing in the appropriate way in phpdbg would break on errors, telling you where the problem originates, possibly. > > So the question is ... just where are the strengths of each and is > either useful for day to day debugging, or more appropriate for > debugging the internal operation of PHP? > A considerable strength of a standalone debugger, is that it is standalone :) You don't need an IDE or any other client, a server, or any other software to debug some code, you just need a debugger. We don't deploy code like this however, so while phpdbg might be able to provide some insight in some cases, xdebug is how we debug code that is deployed in a normal server environment. It depends what you do day-to-day, as mentioned, if you are someone comfortable with, or who spends a considerable amount of time in a console, for whatever reason, then phpdbg can certainly be a useful tool. When it comes to debugging our deployments however, nothing has changed. > -- > Lester Caine - G8HFL > ----------------------------- > Contact - http://lsces.co.uk/wiki/?page=contact > L.S.Caine Electronic Services - http://lsces.co.uk > EnquirySolve - http://enquirysolve.com/ > Model Engineers Digital Workshop - http://medw.co.uk > Rainbow Digital Media - http://rainbowdigitalmedia.co.uk > Cheers Joe -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
