Sure, there are some cases where PHP > functions are too noisy, but that should be addressed instead. You are making the assumption that everybody agrees on E_NOTICE, E_STRICT and E_DEPRECATED being things to be fixed in your code. That is not the case and punishing people for not following exactly the same coding style as you doesn't make sense when it could easily be avoided. Background info: We decided to patch PHP to not generate E_NOTICE for undefined variables or (worse) array offsets because we use this language feature a lot and cannot afford the overhead caused by E_NOTICEs even if error_reporting is set to ignore E_NOTICE. And you won't be able to convince us to change this policy because being able to do things like if (!$visited[$city]++) is more valuable (i.e. keeps the code uncluttered) to us than the E_NOTICE. We use http://cschneid.com/php/phplint.php (in a commit hook) instead to catch typos. It's not perfect but does the job for us. Summary: Don't punish different coding styles unless really necessary.
