PHP i18n::lookup方法代码示例

 /**
  * Format a date
  *
  * Accept either a time stamp, or a formatted string as input parameter:
  * - YYYY-MM-DD HH:MM:SS
  * - YYMMDD HH:MM:SS GMT
  *
  * The variant is processed as follows:
  * - 'day' - only day, month and year --no time information
  * - 'with_hour' - adapts to time scale, and mention hours for today and yesterday
  * - 'no_hour' - adapts to time scale, but don't mention hours
  * - 'full' - display the full date
  * - 'month' - only month and year
  * - 'publishing' - allows for smart skinning
  * - 'standalone' - like full, but without the 'on ' prefix
  * - 'iso8601' - special format
  * - 'plain' - example 'Feb 26 2010 22:30:31 GMT'
  * - 'yyyy-mm-dd' - only day, month and year --no time information
  *
  * The date provided is considered to be GMT-based.
  * It is adjusted to the time zone of the surfer, if applicable.
  * This adjustment does not apply to following variants:
  * - 'day'
  * - 'iso8601'
  * - 'standalone'
  *
  *
  * @link http://www.w3.org/TR/NOTE-datetime the w3c profile of ISO 8601
  * @link http://www.cs.tut.fi/~jkorpela/iso8601.html short description of ISO 8601
  * @link http://fr2.php.net/date Code for ISO 8601 formatting
  *
  * @param int or string the date to be displayed
  * @param string the variant
  * @param string the language to express this stamp
  * @param int offset to GMT of the provided date, if any
  * @return the HTML to be used
