Joindate question.

I have a hack that tracks the last days signups using:

PHP Code:

$registrations=$DB_site->query("SELECT COUNT(*) AS count,username,userid,posts FROM user WHERE joindate > ". mktime(0,0,0,date("m"),date("d"),date("Y")) ." GROUP BY username order by username ASC"); 

What do I change in the code to have it check for the past 7 days?

Thanks!

Use

PHP Code:

$registrations=$DB_site->query("SELECT COUNT(*) AS count,username,userid,posts FROM user WHERE joindate > ". mktime(0,0,0,date("m"),date("d")-7,date("Y")) ." GROUP BY username order by username ASC");
