$lastmonth = mktime(0, 0, 0, date("m")-1, date("d"), date("Y"));

WIth the following

PHP Code:

---

$lastmonth = mktime(0, 0, 0, date("m")-3, date("d"),  date("Y")); 


---

how can I return the result as 2004-11-05?

Have a look at the date function:

PHP Code:

---

$forrmated = date('$Y-$m-$d', $lastmonth); 


---
