  12  * simple usage examples:
  13  * <code>
  14  * // display simple error message 'Error'
  15  * PMA_Message::error()->display();
  16  *
  17  * // get simple success message 'Success'
  18  * $message = PMA_Message::success();
  19  *
  20  * // get special notice 'Some locale notice'
  21  * $message = PMA_Message::notice('strSomeLocaleNotice');
  22  * </code>
  23  *
  24  * more advanced usage example:
  25  * <code>
  26  * // create a localized success message
  27  * $message = PMA_Message::success('strSomeLocaleMessage');
  28  *
  29  * // create another message, a hint, with a localized string which expects
  30  * // two parameters: $strSomeFootnote = 'Read the %smanual%s'
  31  * $hint = PMA_Message::notice('strSomeFootnote');
  32  * // replace %d with the following params
  33  * $hint->addParam('[a@./Documentation.html#cfg_Example@_blank]');
  34  * $hint->addParam('[/a]');
  35  * // add this hint as a footnote
  36  * $hint = PMA_showHint($hint);
  37  *
  38  * // add the retrieved footnote reference to the original message
  39  * $message->addMessage($hint);
  40  *
  41  * // create another message ...
  42  * $more = PMA_Message::notice('strSomeMoreLocale');
  43  * $more->addString('strSomeEvenMoreLocale', '<br />');
  44  * $more->addParam('parameter for strSomeMoreLocale');
  45  * $more->addParam('more parameter for strSomeMoreLocale');
  46  *
  47  * // and add it also to the original message
  48  * $message->addMessage($more);
  49  * // finally add another raw message
  50  * $message->addMessage('some final words', ' - ');
  51  *
  52  * // display() will now print all messages in the same order as they are added
  53  * $message->display();
