PHP IntlDateFormatter - 从日期格式中删除“天”

Question

I want to remove "day" from the pattern to display the correct INTL date in format "F, Y". How to correctly do it without str_replace-ing "d" character with dots (and other symbols) in the $tempPattern variable?

I can't use $formatter->setPattern(), as the date format is different for each language.

function getLocaleDateFormate($locale) {
  $formatter = new IntlDateFormatter($locale, IntlDateFormatter::LONG, IntlDateFormatter::NONE);
  // replace M with L: stand-alone month in year
  $tempPattern = $formatter->getPattern();
  $tempPattern = str_replace("M", "L", $tempPattern);
  return $tempPattern;
}

echo getLocaleDateFormate("sk"); // d. LLLL y
echo getLocaleDateFormate("hu"); // y. LLLL d.
echo getLocaleDateFormate("de"); // d. LLLL y
echo getLocaleDateFormate("es"); // d 'de' LLLL 'de' y
echo getLocaleDateFormate("pl"); // d LLLL y
echo getLocaleDateFormate("cn"); // y年L月d

Answer 1

The output is not in the correct order (it forces the 'LLLL y' order for each language), so I applied the corrections for specific languages. I am not satisfied fully but I don't have any better solution.

if ($locale == "hu") // corrections may apply for specific languages
    $formatter->setPattern("y. LLLL");
elseif ($locale == "cn")
    $formatter->setPattern("y年L月");
else
    $formatter->setPattern("LLLL y"); // stand-alone-monthName Year
return $formatter->getPattern();

I ended up creating a function that would format dates locally, hoping to help !

  const LANG_BACK = 'fr';
  const TIMEZONE = 'Europe/Paris';  

   /**
     * format_date_locale( $date_Object, $dateType , $timeType, $pattern );
     *
     * @param  {object} $date_Object  DateTime object or object accepted
     * @param  {string} $dateType       'NONE', 'SHORT', 'MEDIUM', 'LONG', 'FULL'
     * @param  {string} $timeType       'NONE', 'SHORT', 'MEDIUM', 'LONG', 'FULL'
     * @param  {pattern} $pattern       'MMMM y' -> may 2022
     * see how to set patterns: https://unicode-org.github.io/icu/userguide/format_parse/datetime/#datetime-format-syntax
     * @return {string}                     date formated locally
     */
    format_date_locale( $date_Object, $dateType , $timeType, $pattern ){

            // date format
            switch ( $dateType  ) {
                case 'NONE':
                    $Date_Format = IntlDateFormatter::NONE; // 20220606 08:16 AM
                break;
                case 'SHORT':
                    $Date_Format = IntlDateFormatter::SHORT; // 06/06/2022
                break;
                case 'MEDIUM':
                    $Date_Format = IntlDateFormatter::MEDIUM; // 6 juin 2022 in [fr] must vary
                break;
                case 'LONG':
                    $Date_Format = IntlDateFormatter::LONG; // 6 juin 2022
                break;
                case 'FULL':
                    $Date_Format = IntlDateFormatter::FULL; // lundi 6 juin 2022
                break;

                default:
                    $Date_Format = IntlDateFormatter::SHORT;
                break;
            }

            // time format
            switch ( $timeType  ) {
                case 'NONE':
                    $Time_Format = IntlDateFormatter::NONE; // ''
                break;
                case 'SHORT':
                    $Time_Format = IntlDateFormatter::SHORT; // 08:11
                break;
                case 'MEDIUM':
                    $Time_Format = IntlDateFormatter::MEDIUM; // 08:11:10
                break;
                case 'LONG':
                    $Time_Format = IntlDateFormatter::LONG; // 08:09:33 UTC+2
                break;
                case 'FULL':
                    $Time_Format = IntlDateFormatter::FULL; // 08:10:38 heure d’été d’Europe centrale
                break;

                default:
                    $Time_Format = IntlDateFormatter::SHORT;
                break;
            }

            // create date formatter
            //  LANG_BACK, TIMEZONE, -> const API
            $local_date = IntlDateFormatter::create(
                LANG_BACK, // lang
                $Date_Format, // date
                $Time_Format, // time
                TIMEZONE, // timezone
                null, // type of calendar / null -> const IntlDateFormatter::GREGORIAN
                $pattern // pattern to apply or null
            );

            // return date formatted
            return $local_date->format( $date_Object );

    }
    /**
     * end format_date_locale( $date, $dateType , $timeType, $pattern );
     */

Use :

  $date_Object = new DateTime('now', new DateTimeZone(TIMEZONE) );
  echo format_date_locale( $date_Object, 'FULL' , 'SHORT', null );
  // output : jeudi 9 juin 2022 15:38
