If you have file with name "0" , with
while ($file = readdir($dir)) {
it will be casted to false, but this is regular file. Thus !== is used.

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 m
2 matches
