PHP DateTime

DateTime

DateTime in PHP class is available in PHP 5 and higher versions . This creates a date object which we can use in our script. Here is the code to create a date object and use it .

$today = new DateTime;
echo $today->format('Y-m-d H:i:s');

The above example will display today's date and time in Year-month-date Hour:minutes:second format. Here is the output

2015-02-02 03:02:50

If you are getting warning message saying not to rely on system time zone , then add this line to the top.

date_default_timezone_set('America/Chicago');
$today = new DateTime;
echo $today->format('Y-m-d H:i:s');

Let us try differently

date_default_timezone_set('America/Chicago');
$date = new DateTime("now");
echo $date->format('d-m-y H:i:s');
echo "<br><br>";
$date = new DateTime("tomorrow");
echo $date->format('d-m-y H:i:s');

Out put is here

02-02-15 03:02:50

03-02-15 00:00:00

Another way

date_default_timezone_set('America/Chicago');
$date = new DateTime('2012-04-15 22:15:40');
echo $date->format('Y-m-d H:i:s') ;

Output is here

2012-04-15 22:15:40
