PHP and warnings

manpreet Best Answer 2 years ago

Sometimes when golfing in PHP, one uses tricks as reading/pushing to an inexistent variable, or using deprecated functions such as split(), but those things outputs Warnings and Notices, which by themselves are not really errors and don't change how the code works.

Is there any policy regarding the output of these type of errors?

Should I add provisions to remove or hide the warnings in my code even if the questions doesn't ask it as a requirement or should I consider that the PHP configuration has error_reporting = 0?

I have seen C answers that output compiler warnings (the closest equivalent I can think now)

There currently is no policy about that, but this is my opinion:

• Does the question explicitly disallow code that can lead to a Warning/Notice? Then it is disallowed.
• Does the question say nothing about such code? Then it would say it is allowed (and you can assume that error_reporting = 0), because none of the rules say that it is disallowed.
