      In PHP 4.0.3, <B
CLASS="function"
>dirname()</B
> was fixed to be
      POSIX-compliant. Essentially, this means that if there are no
      slashes in <TT
CLASS="parameter"
><I
>path</I
></TT
> , a dot
      ('<TT
CLASS="literal"
>.</TT
>') is returned, indicating the current
      directory. Otherwise, the returned string is
      <TT
CLASS="parameter"
><I
>path</I
></TT
> with any trailing
      <TT
CLASS="literal"
>/component</TT
> removed. Note that this means that
      you will often get a slash or a dot back from
      <B
CLASS="function"
>dirname()</B
> in situations where the older
      functionality would have given you the empty string.
