I hope this will save some time for others who have to struggle with different php versions on dev and prod plattform in the future:
when formatting a DateTime object with a *custom pattern*, be sure to use a timestamp to pass at the IntlDateFormatter::format in order to have it working on different php versions:
Example for PHP Version 5.3.5-1ubuntu7.2 (my dev machine):
<?php
$date = new \DateTime();
$dateFormatter = \IntlDateFormatter::create(
\Locale::getDefault(),
\IntlDateFormatter::NONE,
\IntlDateFormatter::NONE,
\date_default_timezone_get(),
\IntlDateFormatter::GREGORIAN,
'EEEE'
);
var_dump($dateFormatter->format($date)); // string(6) "Monday"
?>
Example for PHP Version 5.3.2-1ubuntu4.9 (the prod server):
<?php
// same formatting as above
var_dump($dateFormatter->format($date)); // bool(false)
?>
When using $dateFormatter->format($date->getTimestamp()), you'll always get the formatted and localized string instead of a false.
IntlDateFormatter::format
datefmt_format
(PHP 5 >= 5.3.0, PECL intl >= 1.0.0)
IntlDateFormatter::format -- datefmt_format — 日付/時刻 の値を文字列としてフォーマットする
説明
オブジェクト指向型
手続き型
時刻の値を文字列としてフォーマットします。
パラメータ
-
fmt -
Date Formatter リソース。
-
value -
フォーマットする値。DateTime オブジェクト、 Unix タイムスタンプ (epoch からの経過秒数、UTC) を表す整数値、あるいは localtime() 用の配列となります。
返り値
フォーマットされた文字列、あるいはエラーが発生した場合は FALSE を返します。
例
例1 datefmt_format() の例
<?php
$fmt = datefmt_create( "en_US" ,IntlDateFormatter::FULL,IntlDateFormatter::FULL,'America/Los_Angeles',IntlDateFormatter::GREGORIAN );
echo "First Formatted output is ".datefmt_format( $fmt , 0);
$fmt = datefmt_create( "de-DE" ,IntlDateFormatter::FULL,IntlDateFormatter::FULL,'America/Los_Angeles',IntlDateFormatter::GREGORIAN );
echo "Second Formatted output is ".datefmt_format( $fmt , 0);
$fmt = datefmt_create( "en_US" ,IntlDateFormatter::FULL,IntlDateFormatter::FULL,'America/Los_Angeles',IntlDateFormatter::GREGORIAN ,"MM/dd/yyyy");
echo "First Formatted output with pattern is ".datefmt_format( $fmt , 0);
$fmt = datefmt_create( "de-DE" ,IntlDateFormatter::FULL,IntlDateFormatter::FULL,'America/Los_Angeles',IntlDateFormatter::GREGORIAN ,"MM/dd/yyyy");
echo "Second Formatted output with pattern is ".datefmt_format( $fmt , 0);
?>
例2 オブジェクト指向の例
<?php
$fmt = new IntlDateFormatter( "en_US" ,IntlDateFormatter::FULL,IntlDateFormatter::FULL,'America/Los_Angeles',IntlDateFormatter::GREGORIAN );
echo "First Formatted output is ".$fmt->format(0);
$fmt = new IntlDateFormatter( "de-DE" ,IntlDateFormatter::FULL,IntlDateFormatter::FULL,'America/Los_Angeles',IntlDateFormatter::GREGORIAN );
echo "Second Formatted output is ".$fmt->format(0);
$fmt = new IntlDateFormatter( "en_US" ,IntlDateFormatter::FULL,IntlDateFormatter::FULL,'America/Los_Angeles',IntlDateFormatter::GREGORIAN ,"MM/dd/yyyy");
echo "First Formatted output with pattern is ".$fmt->format(0);
$fmt = new IntlDateFormatter( "de-DE" ,IntlDateFormatter::FULL,IntlDateFormatter::FULL,'America/Los_Angeles',IntlDateFormatter::GREGORIAN , "MM/dd/yyyy");
echo "Second Formatted output with pattern is ".$fmt->format(0);
?>
上の例の出力は以下となります。
First Formatted output is Wednesday, December 31, 1969 4:00:00 PM PT Second Formatted output is Mittwoch, 31. Dezember 1969 16:00 Uhr GMT-08:00 First Formatted output with pattern is 12/31/1969 Second Formatted output with pattern is 12/31/1969

You should know that PHPs IntlDateFormatter class uses ISO date format codes instead of PHPs date() format codes. It is not really clear mentioned from my point of view.
A good list to find ISO codes is available at http://framework.zend.com/manual/1.12/en/zend.date.constants.html#zend.date.constants.selfdefinedformats and such a list should be added here, too.

It's important to note that a conversion of timezones will be made from the default timezone (date_default_timezone_set()) and the timezone you passed in the constructor (or datefmt_create()).
If you are inserting the dates into your database as UTC time, make sure to set date_default_timezone_set to UTC as well (or any other timezone, but they need to be the same). Once you call ::format, you will get the converted time.
