php - Return current date plus 7 days

Question

I'm Trying to get the current date plus 7 days to display.

Example: Today is August 16, 2012, so this php snippet would output August 23, 2012.

   $date = strtotime($date);
   $date = strtotime("+7 day", $date);
   echo date('M d, Y', $date);

Right now, I'm getting: Jan 08, 1970. What am I missing?

Answer 1

strtotime will automatically use the current unix timestamp to base your string annotation off of.

Just do:

$date = strtotime("+7 day");
echo date('M d, Y', $date);

Added Info For Future Visitors: If you need to pass a timestamp to the function, the below will work.

This will calculate 7 days from yesterday:

$timestamp = time()-86400;

$date = strtotime("+7 day", $timestamp);
echo date('M d, Y', $date);
