  <para>
   Returns an associative array of strings representing the fetched row in the result
   set, where each key in the array represents the name of one of the result
   set's columns or &null; if there are no more rows in resultset.
  </para>
  <para>
   If two or more columns of the result have the same field names, the last
   column will take precedence. To access the other column(s) of the same
   name, you either need to access the result with numeric indices by using
   <function>mysqli_fetch_row</function> or add alias names.
