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

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
