PHP sfCultureInfo::getTimeZones方法代码示例

/**
 * Returns a <select> tag populated with all the timezones in the world.
 *
 * The select_timezone_tag builds off the traditional select_tag function, and is conveniently populated with 
 * all the timezones in the world (sorted alphabetically). Each option in the list has a unique timezone identifier 
 * for its value and the timezone's locale as its display title.  The timezone data is retrieved via the sfCultureInfo
 * class, which stores a wide variety of i18n and i10n settings for various countries and cultures throughout the world.
 * Here's an example of an <option> tag generated by the select_timezone_tag:
 *
 * <b>Options:</b>
 * - display - 
 *     identifer         - Display the PHP timezone identifier (e.g. America/Denver)
 *     timezone          - Display the full timezone name (e.g. Mountain Standard Time)
 *     timezone_abbr     - Display the timezone abbreviation (e.g. MST)
 *     timzone_dst       - Display the full timezone name with daylight savings time (e.g. Mountain Daylight Time)
 *     timezone_dst_abbr - Display the timezone abbreviation with daylight savings time (e.g. MDT)
 *     city              - Display the city/region that relates to the timezone (e.g. Denver)
 * 
 * <samp>
 *  <option value="America/Denver">America/Denver</option>
 * </samp>
 *
 * <b>Examples:</b>
 * <code>
 *  echo select_timezone_tag('timezone', 'America/Denver');
 * </code>
 *
 * @param  string field name 
 * @param  string selected field value (timezone identifier)
 * @param  array  additional HTML compliant <select> tag parameters
 * @return string <select> tag populated with all the timezones in the world.
 * @see select_tag, options_for_select, sfCultureInfo
