Wrong! Take a look at the SET datatype http://dev.mysql.com/doc/refman/4.1/en/set.html. This allows you to have an array of values in a single field, and the user can select any number of them.

Sort of, but not really: This is a really specialized keyword, and depends on binary mapping of enum-ish sets. As a results you have a maximum of 64 possible values, and only 1 dimension. Large or multdimensional arrays wouldn't work with this.
