Php multilanguage date: howto?

问题

Nota: this is not a duplicate of Translating PHP date() for Multilingual Site . I've read it!

I'm sorry, I first have to explain how my framework works, so you can understand precisely where my problem is:

Here's how my Php code works (rough principles). Let's use for an example someone who wants to see the URL http://myweb.com/valid.php:

in the file valid.php the code include the right classes definition then create one object and call the function display() which displays the page.
in the file valid.php, when the object is created, it analyses the host, and in the host there's the language (http://us.myweb.com/, http://cn.myweb.com/, http://fr.myweb.com/...) and the default language (if none found) is english
then I load a cached Php file where the are the translations. This is a translation object, that I'm calling $t for short
and from now on, whenever I want a translation, I just do things like $t->get('my_string').

Let's take an example with 2 languages file:

2 languages files: cache.us.php and cache.fr.php
in cache.us.php you have a line like this: $thanks_for_the_fish = "Thanks for the fish".
in cache.fr.php you have a line like this: $thanks_for_the_fish = "Merci pour le poisson".
I construct my page, include the right language file then call $t->get('thanks_for_the_fish') and it's translated.

Now my problem comes with date formatting. With short date format it's not a problem:

in cache.us.php: $short_date_format = "m/d/Y, H:i".
in cache.fr.php: $short_date_format = "d/m/Y à H:i".

But with long date format, I'm just working on french and I begun with something like:

in cache.fr.php: $long_date_format = "%s, %d %s %d".
then all the days: $sunday = "dimanche", $monday = "lundi" and so on
then in my translation code:

Something like this (read carefully the comment in the code, my question is in it!):

static private $_TabStrDaysOfWeek = array(
    0 => 'sunday',
    1 => 'monday',
    ...,
    6 => 'saturday'
);
public function translateDate($date_time)
{
    $long_day = $this->tr->get(
        $this->_TabStrDaysOfWeek[ $date_time->format('w') ]
    );
    /*

    here's where I'm stuck:
    what could be the code to be able to display:
    - english:
      Monday, 1st September 2006
      Tuesday, 2nd September 2006
      Wednesday, 3rd September 2006
      Thursday, 4th September 2006

    - french:
      Lundi, 1 septembre 2006
      Mardi, 2 septembre 2006
      Mercredi, 3 septembre 2006
      Jeudi, 4 septembre 2006

    - arabian!!:
      1 - Don't know
      2 - Don't know
      3 - Don't know
      4 - Don't know
    */
}

... And I said arabian because I'll need it sooner or later, same for Mandarin Chinese. All my other translation problems are solved but this one!!

Any idea?

回答1:

For internationalization tasks, I'd strongly recommend using the PHP intl extension. It contains several classes for common internationalization tasks such as date/time formatting, number formatting, string transliteration and more. Specifically, the IntlDateFormatter class is able to format (and parse) a datetime for any available locale.

Here's how I've done it: it seems there's no possibility other than do a switch and handle each language separately:

Here's what's in my cache:

$this->jour_dimanche = dimanche
$this->jour_lundi = lundi
$this->jour_mardi = mardi
$this->jour_mercredi = mercredi
$this->jour_jeudi = jeudi
$this->jour_vendredi = vendredi
$this->jour_samedi = samedi

$this->mois_janvier = janvier
$this->mois_fevrier = février
$this->mois_mars = mars
$this->mois_avril = avril
$this->mois_mai = mai
$this->mois_juin = juin
$this->mois_juillet = juillet
$this->mois_aout = août
$this->mois_septembre = septembre
$this->mois_octobre = octobre
$this->mois_novembre = novembre
$this->mois_decembre = décembre

// long date format = 'day, (month number) (month) (year)'
// '%s, %d %s %d' => 'Mardi, 2 juillet 2012'
$this->date_format_long = %\s, j %\s Y à H:i

...And my Php code:

public function translateDate($date_time, $first_upcase=true)
{   
    switch ($this->_trad->getLang()) {
        /* TODO: all other languages */
        case 'us':
        case 'ar':
        case 'es':
        case 'cn':
            throw new Exception("not handled yet");
            break;

        default:
            /* default = french */
            $day = $this->_trad->get(
                self::$_TabStrDaysOfWeek[ $date_time->format('w') ]
            );  
            $month = $this->_trad->get(
                self::$_TabStrMonths[ $date_time->format('j') ]
            );  
            $ret = sprintf(
                $date_time->format(
                    $this->_trad->get('date_format_long')
                ),  
                $day,
                $month
            );  
            if ($first_upcase) {
                $ret = ucfirst($ret);
            }   
            break;
    }   
    return $ret;
}
