Good evening all!
Currently, if the constant FROB_ACTIVE is not defined, the code "echo
FROB_ACTIVE;" results in an E_NOTICE and the string 'FROB_ACTIVE' being
displayed. I would like to propose that this be changed to an E_WARNING
in PHP 7.2, and to an Error in PHP 8.0.
My reasoning for this includes:
- consistency with other "undefined" errors, including the otherwise
identical "echo \FROB_ACTIVE;"
- the fallback to string appears to be largely undocumented except to
discourage its use
- the error can mask serious bugs, such as when mis-typing keywords
I have tried to anticipate some of the questions that will be raised, so
have drafted an RFC rather than trying to fit all the detail into one
e-mail: https://wiki.php.net/rfc/deprecate-bareword-strings
Please read my proposal, and let me know your thoughts. I have placed
the RFC "under discussion", but will be happy to modify it based on
feedback, and am in no haste to put it to a vote.
Regards,
