resource id #5 atd. ti vypisuje pretoze nepouzivas mysql_fetch_array alebo mysql_fetch_assoc.
s najvacsou pravdepodobnostou mas problem s diakritikou.

cize daj sem co ti vypise v sqlku tento dotaz:
show variables where variable_name like '%coll%';

malo by to vyplut nieco podobne:

+----------------------+----------------+
| Variable_name        | Value          |
+----------------------+----------------+
| collation_connection | utf8_slovak_ci |
| collation_database   | utf8_slovak_ci |
| collation_server     | utf8_slovak_ci |
+----------------------+----------------+
