        Libxml 2 unescapes the URI, so if you want to pass e.g.
        <TT
CLASS="literal"
>b&#38;c</TT
> as the URI parameter <TT
CLASS="literal"
>a</TT
>,
        you have to call
        <TT
CLASS="literal"
>simplexml_load_file(rawurlencode('http://example.com/?a=' .
        urlencode('b&#38;c')))</TT
>. Since PHP 5.1.0 you don't need to do
        this because PHP will do it for you.
