PHP 7.3 compatibility
PHP 7.3 was released Dec 6, 2018.
Confirm PHP 7.3 compatibity, create tasks in this issue or other related ones if they are found, then update https://docs.civicrm.org/sysadmin/en/latest/requirements/ to indicate PHP 7.3 is supported.
There are a number of Backward Incompatible Changes in 7.3 that may affect us: http://php.net/manual/en/migration73.incompatible.php
- continue statements targeting switch control flow structures will now generate a warning
There don't seem to be that many places where this might be an issue: ``grep -R -n -i -A5 -B5 "continue" ./* | grep -E 'continue|switch' | more
- Strict Interpretation of Integer String Keys on ArrayAccess
Whack-a-mole efforts may be needed.
I think if enough reports of successful use of 7.3 are found then we should go ahead and update the documentation. I will encourage dev chat channel to weigh in here.
