今天从00:00到现在如何获得今天的时间跨度？

Question

There is a lot to find about all different Date or Time calculations, but I was unable to locate the method to get exactly what I need.

I need to retrieve all history (traffic) from the database at any given time of day. I am using $from and $till for this. $till is easy because I fetch that with;

$till= new \DateTime();

wich shows as: 2014-06-05 16:21:53

I need to fill $from with: 2014-06-05 00:00:00

I think it will be very easy when I see the answer, but for now I am failing at achieving this.

Answer 1

Just format $till with the time you desire:

$till= new \DateTime();
$from = $till->format('Y-m-d 00:00:00');

Demo

You can also do:

$from = new \DateTime('midnight')
