Selectable error messages

OK - I've got PHP5.3.0-dev up at the moment in order to test the Firebird stuff, so display_errors is on. I need it on anyway while testing code. The 'problem' I am having is that of cause none of the other PHP stuff I'm using is currently not compatible with PHP5.3 so generates a lot of deprecated warnings in particular. Current one is phpDocumentor which uses is_a() extensively, and has a function to replicate it for backwards compatibility. Short of switching display_errors on and off all the time, how do other people handle this irritation? I could repair phpDocumentor in this case and ignore BC as I will not be running THAT on older version of PHP, and since a run is taking 30 minutes it would be interesting to see if there is any improvement to time. .... bit the bullet - my copy of phpDocumentor has no is_a() in it .... -- Lester Caine - G8HFL ----------------------------- Contact - http://lsces.co.uk/lsces/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk// Firebird - http://www.firebirdsql.org/index.php
