ah, no, these answers are exactly right, given that $a is an integer,

so the comparisons are true. #2 compares two different strings and so
is false. #4 compares 0 to the integer of unset and so is true. #5 and
#6 compare strings to the string of unset and so are false.
Yes, this is what PHP does. It's just that what PHP does is insane. It
does not match any normal, logical thought process.
Insane may be overly harsh -- how about 'unorthodox'?
It does strike me, though, that there are an awfully large
number of questions to the internals list asking whether a
certain behavior is expected or not.
