  <para>
   Fetches one row of data from the result set and returns it as an object,
   where each property represents the name of the result set's column.
   Each subsequent call to this function will return the next row within the
   result set, or &null; if there are no more rows.
  </para>
  <para>
   If two or more columns of the result have the same name, the last
   column will take precedence and overwrite any previous data. To
   access multiple columns with the same name,
   <function>mysqli_fetch_row</function> may be used to fetch the numerically
   indexed array, or aliases may be used in the SQL query select list to give
   columns different names.
  </para>
  <note xmlns="http://docbook.org/ns/docbook">
   <simpara>
     This function sets the properties
     of the object before calling the object constructor.
