I've rebuilt my container to use php7.2.1 and it's exactly the same.

And are you sure *execution* stops or can you simply not see the output? Try something like touch()ing a file. ------------------------------------------------------------------------ [2018-01-24 18:03:30] km dot wrona at gmail dot com Description: ------------ header() terminates execution when content-length is 0 This happens on Alpine3.7 php 7.1.12, for some reason not available in the list above.
