Seems like I used to use this exact idiom under PHP 5, and it worked,
but under PHP 7 it doesn't.
Am I mis-remembering? If not, is there some common way around this
under
PHP 7?
I can't speak to whether this would have worked in PHP 5 (I'm new
enough to PHP that I started out on 7), but I think the fix you want is
the new null coalescing operator ("??"), like this:
<?php echo $_POST['pizza'] ?? ''; ?>
