 New Comment:

This issue is by now more than 7 years old and targets an unsupported version of PHP.

Using a supported version of PHP you can do this via:

$date = new DateTime('2009-07-07 13:20:12');
$formatter = new IntlDateFormatter(
    'de-DE',
    IntlDateFormatter::FULL, 
    IntlDateFormatter::FULL, 
    $date->getTimezone(), 
    IntlDateFormatter::GREGORIAN, 
    'EEEE'
);
echo $formatter->format($date);

I'm therefore closing this as fixed.

date_format / DateTime::format can't be changed to use locales, because that would break a lot
of programs.

A new function date_format_locale / DateTime::formatLocale would be an excellent addition. 

I use this as a workaround now:

<?php
function date_format_locale(DateTime $dt, $format)
{
	$len = strlen($format);
	if (strcspn($format, 'DlFM') >= $len) {
		return $dt->format($format);
	}
	$marker = "\x0B";
	$keys = array('D' => '%a', 'l' => '%A', 'F'
=> '%B', 'M' => '%b');
	$start = 0;
	while (($start += strcspn($format, 'DlFM\\', $start)) < $len) {
		$char = $format[$start];
		if ('\\' === $char) {
			$start += 2;
		} else {
			$format[$start++] = $marker;
			$replacements[] = $keys[$char];
		}
	}
	if (!isset($replacements)) {
		return $dt->format($format);
	}
	list($wday, $month) = explode(' ', $dt->format('w n'));
	$wday = (int) $wday;
	$month = (int) $month;
	$sundays = array(0, 2, 6, 6, 3, 1, 5, 3, 7, 4, 2, 6, 4);
	$day = $sundays[$month] + $wday;
	$ts = gmmktime($hour=0, $minute=0, $second=0, $month, $day, $year=2011);
	$replacements = explode($marker, gmstrftime(implode($marker, $replacements), $ts));
	$ret = $dt->format($format);
	while (false !== $i = strpos($ret, $marker)) {
		$str = array_shift($replacements);
		//$str = mb_convert_case($str, MB_CASE_TITLE);
		$ret = substr_replace($ret, $str, $i, 1);
	}
	return $ret;
}
?>

Hope this helps, best regards!

This is indeed planned for PHP 6, where there is an experimental function
"date_format_locale()" already—but that is bound to change.

Description:
------------
as of 5.2 there are features of DateTime class.
http://de.php.net/datetime

Im asking myself at the moment, why it does not look up locales. It is somehow stupid to use
datetime, convert it to timestamp just to get an output of the month for any language, assuming
strftime to convert the timestamp.

I hope this will be changed. 

Reproduce code:
---------------
<?php  
  echo '<pre>';
  $date1 = new DateTime('2009-07-07 13:20:12');
  setlocale(LC_ALL, 'German');
  var_dump(strftime('%A', $date1->format('U')));
  var_dump($date1->format('l'));
  setlocale(LC_ALL, 'English');
  var_dump(strftime('%A', $date1->getTimestamp()));
  var_dump($date1->format('l'));
  echo '</pre>';
  highlight_file(__FILE__);
?> 

Expected result:
----------------
string(8) "Dienstag"
string(7) "Dienstag"
string(7) "Tuesday"
string(7) "Tuesday"


Actual result:
--------------
string(8) "Dienstag"
string(7) "Tuesday"
string(7) "Tuesday"
string(7) "Tuesday"
