PHP Locales::getPluginLocale方法代码示例

 /**
  * @static
  * Static method that offers some kind of locale factory. Since the Locale object
  * better not use a Singleton (otherwise we couldn't use more than one locale file
  * at a time) this function has been included here to provide a system similar to
  * a singleton: we keep an static array inside the function, that contains all the
  * locale files that have been loaded so far. Whenever somebody requests a locale
  * to be fetched from disk, we will first check that we have not loaded it before. If
  * we have, then we only have to return the same object we were keeping.
  * If the locale wasn't there, we will then load it from disk and store/cache the
  * resulting object for future use.
  * It is recommended to use this method over creating new Locale objects every time
  * we need one.
  *
  * @param localeCode The code (eg. en_UK, es_ES) of the locale we want to get.
  * @return Returns a Locale object corresponding to the requested locale.
  * @see Locale
