note 11752 modified in Operators by torben

logically, this is just plain wrong, but in php-land, it's right: 0 == false "" == false 0 == "" 0 == "0" try this with any other string that isn't the empty string, and i think that you'll find it evaluates to true. now, i'm a little rusty on basic set theory, but lemme see if i can remember lesson one: it goes something like, "the empty set is NOT EQUAL to the set with the empty set as its only element." i hope someday i'll check back on this little note, and some editor will have provided a worthy explanation as to why this was allowed. http://www.php.net/manual/operators.php
