   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>
   <function>mysqli_fetch_array</function> is an extended version of the
   <function>mysqli_fetch_row</function> function. In addition to storing the
   data in the numeric indices of the result array, the 
   <function>mysqli_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.

       This optional 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 <constant>MYSQLI_ASSOC</constant>,
       <constant>MYSQLI_NUM</constant>, or <constant>MYSQLI_BOTH</constant>.
      </para>
      <para>
       By using the <constant>MYSQLI_ASSOC</constant> constant this function
       will behave identically to the <function>mysqli_fetch_assoc</function>,
       while <constant>MYSQLI_NUM</constant> will behave identically to the
       <function>mysqli_fetch_row</function> function. The final option 
       <constant>MYSQLI_BOTH</constant> will create a single array with the
       attributes of both.
