Okay, if $cat_id is 53, this will work out to:
if(FALSE || TRUE || TRUE || TRUE || TRUE || TRUE)
which results in TRUE overall.
You want && instead of ||
if ($cat_id != "53" && $cat_id != "54" && $cat_id !=
"55" && $cat_id
!= "117" && $cat_id != "118" && $cat_id != "74")
which results in
if(FALSE && TRUE && TRUE && TRUE && TRUE && TRUE)
which results in FALSE overall.
