The new sql() is returning an object because that is what your asking for.
now if you did a $db->sql() that'd return false.
yes you did put a return false in the constructor but an object is what is
being created and thus what is being returned. In my opinion a return
anything within the constructor shouldn't be allowed. This might be the
behavior in newer versions but I don't know.
newer syntax is:
class sql {
function __construct (...) {
...
}
}
truthfully when you do the $db = new sql(...); you are not running that
function.. you are instantiating a new instance of sql which is invoking the
object's constructor.
