    <para>
     Returns an array that corresponds to the fetched row or &null; if there are no more rows for the
     resultset represented by the <parameter>result</parameter> parameter. 
    </para>
    <para>
     <function>maxdb_fetch_array</function> is an extended version of the
     <function>maxdb_fetch_row</function> function. In addition to storing the data in the
     numeric indices of the result array, the <function>maxdb_fetch_array</function> function can
     also store the data in associative indices, using the field names of the result set as keys.
    </para>
    &database.field-case;
    &database.fetch-null;
    <para>
     If two or more columns of the result have the same field names, the last column will take
     precedence and overwrite the earlier data. In order to access multiple columns with the same
     name, the numerically indexed version of the row must be used.
    </para>
    <para>
     The optional second argument <parameter>resulttype</parameter> is a constant indicating what
     type of array should be produced from the current row data. The possible values for this parameter
     are the constants MAXDB_ASSOC, MAXDB_ASSOC_UPPER, MAXDB_ASSOC_LOWER, MAXDB_NUM, or MAXDB_BOTH. 
     By default the
     <function>maxdb_fetch_array</function> function will assume MAXDB_BOTH, which is a combination of
     MAXDB_NUM and MAXDB_ASSOC  for this parameter.
    </para>
    <para>
     By using the MAXDB_ASSOC constant this function will behave identically to the
     <function>maxdb_fetch_assoc</function>, while MAXDB_NUM will behave identically to the
     <function>maxdb_fetch_row</function> function. The final option MAXDB_BOTH will create a single
     array with the attributes of both.
    </para>
    <para>
     By using the MAXDB_ASSOC_UPPER constant, the behaviour of this function is identical to the use
     of MAXDB_ASSOC except the array index of a column is the fieldname in upper case.
    </para>
    <para>
     By using the MAXDB_ASSOC_LOWER constant, the behaviour of this function is identical to the use
     of MAXDB_ASSOC except the array index of a column is the fieldname in lower case.
