The fields parameter
is an array of arrays, each array describing the format of
one field in the database. Each field consists of a name, a
character indicating the field type, a length, and a
precision.
The types of fields available are:
Boolean. These do not have a length or
precision.
Memo. (Note that these aren't supported by PHP.)
These do not have a length or precision.
Date (stored as YYYYMMDD). These do not have a
length or precision.
Number. These have both a length and a precision
(the number of digits after the decimal point).
String.
If the database is successfully created, a
dbase_identifier is returned, otherwise
FALSE is returned.
