php date format

Question

I have a date in a variable like: 01-01-2009 and need to change the format to Y-m-d. What should I use to do this conversion?

Answer 1

You can use the strtotime and date functions like this:

$str = '01-01-2009';
$date = date('Y-m-d', strtotime($str));

echo $date; //2009-01-01
