the result of == is boolean, not the arguments
expected behaviour could be:
if left-hand-type != right-hand-type
convert right-hand-argument to left-hand type
compare left-hand-argument to possibly converted right-hand-argument
additionaly, IMHO,
as php has to deal with html forms a lot and html has no
<input type=numeric> there are a lot of places where a string
that qualifies as is_numeric is silently treated as a numeric argument
=== , on the other hand, works like this:
if left-hand-type != right-hand-type
result is false
else
compare unconverted left-hand-argument to unconverted
right-hand-argument
