php8: the result of a call assigned by reference

php8: the result of a call assigned by reference

"Only variables should be assigned by reference": the return value of a
function is not a variable, and none of the three methods called declares
that it returns a reference. With objects the & has been useless since php 5,
and every other place that calls get_user() already assigns without it.

The Notice came out on every card played (briskin5's index_wr.php) and was
invisible until the daemon log was cleaned up.
