I'm not sure if a resource casted to numeric to be 0 - var_dump() to say :(0) resource
of type ....
!==flase assures that it is FALSE, not 0.
!== is like != but makes type checking. Frequently used with strpos(). See the memos
there.
There is also available === operator. It is like == but also makes type comparison.
