more variable in my conditional

[bartek24m]

i would like modyfy just one line of php code in my hook

PHP Code:

$isforumid = 189 === $thread['forumid']; 


It works when is written only one forum id.
i would like to add up more numbers to this conditional but i dont know how.


i tried change code in to this:
$isforumid = array(1,2,3,4,5,189) === $thread['forumid'];
but it doesnt work

any ideas?
