Convert datetime to RFC 3339

Question

My input date is 2014-03-10 05:40:00. How can I convert it to RFC format like 2014-3-10T05:40:00.000-00:00?

Answer 1

RFC3339 is one of the predefined format constants of the DateTime class.

$inputDate = "2014-03-10 05:40:00";

$datetime = \DateTime::createFromFormat("Y-m-d H:i:s", $inputDate);

echo $datetime->format(\DateTime::RFC3339);

Answer 2

here another option added in php5 like this

$datetime= date("c", strtotime("2014-03-10 05:40:00"));
echo $datetime;  //Output : 2014-03-10T05:40:00+00:00 

Answer 3

I'd like to add that the predefined constants for this can also be used with date(). Both:

date(DATE_RFC3339);

and

date(DATE_ATOM);

return an RFC3339 formatted date time string and are the equivalent of:

date('Y-m-d\TH:i:sP');
