function date_format_date

Formats a date, using a date type or a custom date format string.

Reworked from Drupal's format_date function to handle pre-1970 and post-2038 dates and accept a date object instead of a timestamp as input. Translates formatted date results, unlike PHP function date_format(). Should only be used for display, not input, because it can't be parsed.

Parameters

object $date: A date object.

string $type: (optional) The date format to use. Can be 'small', 'medium' or 'large' for the preconfigured date formats. If 'custom' is specified, then $format is required as well. Defaults to 'medium'.

string $format: (optional) A PHP date format string as required by date(). A backslash should be used before a character to avoid interpreting the character as part of a date format. Defaults to an empty string.

string $langcode: (optional) Language code to translate to. Defaults to NULL.

Return value

string: A translated date string in the requested format.
