Example4
Below example creates a new date using the date_format() function -
<?php $dateSrc = '2005-04-19 12:50 GMT'; $dateTime = date_create( $dateSrc);; # Now set a new date using date_format(); date_format( $dateTime, 2000, 12, 12); echo "New Formatted date is ". $dateTime->format("Y-m-d\TH:i:s\Z"); echo "
"; # Using second function. $dateTime = new DateTime($dateSrc); $dateTime->setDate( 1999, 10, 12); echo "New Formatted date is ". $dateTime->format("Y-m-d\TH:i:s\Z"); ?>
Output
When the above code is executed, it will produce the following result -
New Formatted date is 2000-12-12T12:50:00Z New Formatted date is 1999-10-12T12:50:00Z
