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