How to convert Y-m-d H:i:s to Y-m-d in PHP?

I have e.g.

$date = "2011-08-10 20:40:12";

and would like to convert it to just

$output = "2011-08-10";

Thanks in advance.

Answer 1

quick/dirty:

$output = substr('2011-08-10 20:40:12', 0, 10);

slightly more robust:

$output = date('Y-m-d', strtotime('2011-08-10 20:40:12'));

fairly reliable:

$output = DateTime::createFromFormat('Y-m-d h:i:s', '2011-08-10-20:40:12')->format('Y-m-d');

Answer 2

Easily done with strtotime(), and capable of changing to any other date format you may need as well.

$old_date = "2011-08-10 20:40:12";
$new_date = date("Y-m-d", strtotime($old_date));
echo $new_date;

// Prints 2011-08-10
