ZipArchive::getArchiveFlag `flags` parameter description

[alfsb]

From manual page: https://php.net/ziparchive.getarchiveflag , the source is:

     <term><parameter>flags</parameter></term>
     <listitem>
      <para>
       If <parameter>flag</parameter>s is set to <constant>ZipArchive::FL_UNCHANGED</constant>,
       the original unchanged flag is returned.
      </para>
     </listitem>

Note that there is a s right after <parameter>flag</parameter>, so this appear to be a typo.
