>&#13;     This function discards the contents of the topmost output buffer and
     turns off this output buffering. If you want to further
     process the buffer's contents you have to call
     <A
HREF="function.ob-get-contents.html"
><B
CLASS="function"
>ob_get_contents()</B
></A
> before
     <B
CLASS="function"
>ob_end_clean()</B
> as the buffer contents are
     discarded when <B
CLASS="function"
>ob_end_clean()</B
> is called.
     The function returns <TT
CLASS="constant"
><B
>TRUE</B
></TT
> when it successfully 
     discarded one buffer and <TT
CLASS="constant"
><B
>FALSE</B
></TT
> otherwise. Reasons for failure are first
     that you called the function without an active buffer or that for some
     reason a buffer could not be deleted (possible for special buffer).
