As the manual suggests, using the === operator to check for FALSE is
probably the best way.

Using |= directly on these things is probably going to get ugly
quickly, as you will probably need something more like:
$isSpam |= (strstr($_POST['Name'],'@')===false ? 1:0);
Stepping back from the minutae of coding style...
Writing your own spam filter is probably a Bad Idea, as re-inventing
this particular wheel is far more effort than you have yet realized,
and PHP is almost certainly the wrong weapon in the first place...
I say this, having attempted to do it myself. :-)
Install Spam Assassin or something similar, and get way better results.
