    <note>
     <para>
      <function>implode</function> can, for historical reasons, accept
      its parameters in either order. For consistency with
      <function>explode</function>, however, it may be less confusing
      to use the documented order of arguments.
     </para>

    <note>
     <para>
      As of PHP 4.3.0, the glue parameter of <function>implode</function> is
      optional and defaults to the empty string(''). This is not the preferred
      usage of <function>implode</function>. We recommend to always use two
      parameters for compatibility with older versions.
