wp_date:这是一个WordPress函数,它根据站点的设置设置日期格式。它可以用于以特定格式显示日期或获取当前日期。

检索日期,以本地化的格式。

这是一个较新的函数,旨在取代`date_i18n()`,没有遗留的怪癖。

注意,与`date_i18n()`不同,这个函数接受真正的Unix时间戳,而不是与时区偏移相加。

function wp_date( $format, $timestamp = null, $timezone = null ) {
	global $wp_locale;

	if ( null === $timestamp ) {
		$timestamp = time();
	} elseif ( ! is_numeric( $timestamp ) ) {
		return false;
	}

	if ( ! $timezone ) {
		$timezone = wp_timezone();
	}

	$datetime = date_create( '@' . $timestamp );
	$datetime->setTimezone( $timezone );

	if ( empty( $wp_locale->month ) || empty( $wp_locale->weekday ) ) {
		$date = $datetime->format( $format );
	} else {
		// We need to unpack shorthand `r` format because it has parts that might be localized.
		$format = preg_replace( '/(?<!\\)r/', DATE_RFC2822, $format );

		$new_format    = '';
		$format_length = strlen( $format );
		$month         = $wp_locale->get_month( $datetime->format( 'm' ) );
		$weekday       = $wp_locale->get_weekday( $datetime->format( 'w' ) );

		for ( $i = 0; $i < $format_length; $i ++ ) {
			switch ( $format[ $i ] ) {
				case 'D':
					$new_format .= addcslashes( $wp_locale->get_weekday_abbrev( $weekday ), '\A..Za..z' );
					break;
				case 'F':
					$new_format .= addcslashes( $month, '\A..Za..z' );
					break;
				case 'l':
					$new_format .= addcslashes( $weekday, '\A..Za..z' );
					break;
				case 'M':
					$new_format .= addcslashes( $wp_locale->get_month_abbrev( $month ), '\A..Za..z' );
					break;
				case 'a':
					$new_format .= addcslashes( $wp_locale->get_meridiem( $datetime->format( 'a' ) ), '\A..Za..z' );
					break;
				case 'A':
					$new_format .= addcslashes( $wp_locale->get_meridiem( $datetime->format( 'A' ) ), '\A..Za..z' );
					break;
				case '\':
					$new_format .= $format[ $i ];

					// If character follows a slash, we add it without translating.
					if ( $i < $format_length ) {
						$new_format .= $format[ ++$i ];
					}
					break;
				default:
					$new_format .= $format[ $i ];
					break;
			}
		}

		$date = $datetime->format( $new_format );
		$date = wp_maybe_decline_date( $date, $format );
