How to calculate days between two dates in PHP?

I need to calculate the days between the date I get from the database and the current date.

$upload_date = mysql_query("SELECT Date FROM Setting WHERE ID = $row[ID]");
$current_date = date("Y-m-d");

How should I do it?

If you want to do this in PHP, use the DateTime class :

$current = new DateTime($current_date);
$db_date = new DateTime($upload_date);
$days = $current->diff($db_date)->days;

Or the oldschool path:

$days = round((strtotime($current) - strtotime($db_date)) /24 /60 /60);

you can do it in a simple way as shown below

$current_date = date("Y-m-d");          // Current date
$db_date = date("Y-m-d");               // Date from your database
$diff = abs(strtotime($current_date) - strtotime($db_date));
$total_days = floor ($diff /  (60*60*24));
