Help with date/time in PHP

I am trying to code the following:

$expires = current date + 7 days



and


if current date > $expires echo('expired');


can anyone help?

 

PHP:

1.  
2. $now = time();    // current unix timestamp
3. $day = 3600 * 24; //numbers of seconds per day
4.  
5. $expires = $now + 7*$day;
6.  

PHP:

1.  
2. $now = time(); // current unix timestamp
3. if($now > $expires)
4.   echo ('expired');
5.  

 

how would you display the actual time from that value?

 

PHP:

1.  
2. $time = time(); //current time stamp
3. echo strftime ("%D", $time);
4.  

To know what the %D means, and other possibilities you have, you must read this page http://www.php.net/strftime
