Hi Adrian,
Suppose you have a DateFormatter class, then you could define an array
with a date format for each locale, and one with separators, like:
function initFormatsAndSeparators () {
$this->dateformats["en-us"] = "mm/dd/yyyy";
$this->dateSeparators["en-us"] = '/'.
$this->dateformats["du-nl"] = "yyyy-mm-dd";
$this->dateSeparators["du-nl"] = '-'.
}
now you can split a date like this:
function splitDT($value, $locale)
{
$expr = '['.$this->dateSeparators[$locale].']';
$arr = split($expr, $value);
$formatArray = split($expr, $this->dateformats[$locale]);
for ($i=0; $i<count($formatArray); $i++)
$result[$formatArray[$i]] = $arr[$i];
return $result;
}
This gives you an array like:
array('yyyy' => '2004', 'mm' => '7', 'dd' => '18')
formatting suchg a splitted date into another format can then be done like:
function formatDate($splittedDate, $locale)
{
$result = $this->dateFormats[$locale];
forEach($splittedDate as $key => $value)
$result = str_replace($key, $value, $result);
return $result;
}
Of course there will be more to it then this, for example you may want
to convert 'mm' => '7' into 'mm' => '07' and check that the value for
'mm' is no larger then 12. Or you might want to process month names.
This will probably lead to a case switch with a case for 'mm' and one
for for 'yyyy' etc. that you run through while looping through the
$splittedDate array. But at least that case switch will be a lot smaller
then a case for each and every locale.
BTW, did you check out
http://pear.php.net/package/Date ?
(please let me know if you find a workaround for it's dependency on
setLocale based functions ;-) )

I have a server app which is sent a date in the local format of the client
machine. I've no control over the client app at all, so have to code at the
server end to cope with any problems. The server is in the US, so any
dates need to be in US format before they will convert using strtotime()
Here is what i'm doing at the moment..
// need to convert date to use USA mm/dd/yyyy format on server
$split = explode(",",$_SERVER[HTTP_ACCEPT_LANGUAGE]);
switch ($split[0]) {
case "en-us":
break;
case "en-gb":
$lt = substr($lt,3,3) . substr($lt,0,3) . substr($lt,6);
break;
case "da":
case "pt":
$lt = substr($lt,3,2) . "/" . substr($lt,0,2) . "/" . substr($lt,6);
break;
}
$ustime = strtotime($lt);
As you can see, the switch could get huge.. Is there any easier way ?
Thanks
Adrian
