Digg date_create
Returns new DateTime object
(PHP 5 >= 5.1.0)
Parameters
Code Examples / Notes » date_createjsnell
When using these functions inside of destructors or functions called as a result of being registered with register_shutdown_handler, be sure to use date_create() instead of new DateTime(). This is because new DateTime will throw an exception on failure, which is not permitted in any of the above circumstances. If new DateTime() does fail in one of these circumstances, you will get an error stating "Fatal error: Exception thrown without a stack frame in Unknown on line 0."

The manual says "Returns DateTime object on success or FALSE on failure". I tried hard to provoke a failure, but I seem to always get a DateTime object back, even though the PHP log says things like: "Failed to parse time string (2007W992-11:16:47+00:00) at position 5 (9): Unexpected character" So if you (need to) check the result, beware! dok
If you want to create the DateTime object directly from a timestamp use this <? $st = 1170288000 // a timestamp $dt = new DateTime("@$st"); ?> See also: http://bugs.php.net/bug.php?id=40171 nizar dot jouini
date_create and other DateTime related functions are included by default only in PHP versions equal and greater than 5.2. In PHP 5.1.2 this functionality is marked to be experimental and has to be enabled at compile time. artur
"String in a format accepted by strtotime()" is not 100% truth - you cannot pass timezone info in the string used as DateTime constructor, while you can do it with strtotime(). It may be a problem if you would like to create a date from GMT time and then display it in your local timezone, for example: <?php $timeZone = 'Europe/Warsaw'; // +2 hours date_default_timezone_set($timeZone); $dateSrc = '2007-04-19 12:50 GMT'; $dateTime = new DateTime($dateSrc); echo 'date(): '.date('H:i:s', strtotime($dateSrc)); // correct! date(): 14:50:00 echo 'DateTime::format(): '.$dateTime->format('H:i:s'); // INCORRECT! DateTime::format(): 12:50:00 ?> So if you want to convert date between different timezones, you have to create two DateTimeZone objects - one for the input and one for output, like this: <?php $timeZone = 'Europe/Warsaw'; // +2 hours $dateSrc = '2007-04-19 12:50'; $dateTime = new DateTime($dateSrc, new DateTimeZone('GMT')); $dateTime->setTimeZone(new DateTimeZone($timeZone)); echo 'DateTime::format(): '.$dateTime->format('H:i:s'); // CORRECT! DateTime::format(): 14:50:00 ?> I'm not sure if this is a bug or desired behaviour. |
