I think I've sorted it out .... at least I know why it doesn't work:
bool in_array ( mixed needle, array haystack [, bool strict])
Searches haystack for needle and returns TRUE if it is found in the
array, FALSE otherwise. If the third parameter strict is set to TRUE
then the in_array() function will also check the types of the needle in
the haystack. Note: If needle is a string, the comparison is done in a
case-sensitive manner.
Note: In PHP versions before 4.2.0 needle was not allowed to be an array.
PHP on the server is 4.1.2 !!!
Is a foreach loop the only thing that I can do???

Ricky
