      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 <VAR
CLASS="parameter"
>path</VAR
> , a dot
      ('<VAR
CLASS="literal"
>.</VAR
>') is returned, indicating the current
      directory. Otherwise, the returned string is
      <VAR
CLASS="parameter"
>path</VAR
> with any trailing
      <VAR
CLASS="literal"
>/component</VAR
> 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.
     </P

><P
>&#13;     <B
CLASS="function"
