  <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.

  <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.
