Dynamic Date List Newbie Problem

Hi folks, My goal was to create a dynamic date related list as follows: - take the current date (3/12/2009) - create a new date from it which would be the *1st* of that month - (3/1/2009) - then create a list that shows the current and previous 11 months like: 03/1/09 02/1/09 01/1/09 12/1/08 11/1/08 etc... --- so I did this (not fancy but was working) $nowts = strtotime(date("m")."/1/".date("y")); $m01 = date('m',$nowts-(0))."/1/".date('y',$nowts-(0)); $m02 = date('m',$nowts-(86400*30))."/1/".date('y',$nowts-(86400*30)); $m03 = date('m',$nowts-(86400*60))."/1/".date('y',$nowts-(86400*60)); $m04 = date('m',$nowts-(86400*90))."/1/".date('y',$nowts-(86400*90)); $m05 = date('m',$nowts-(86400*120))."/1/".date('y',$nowts-(86400*120)); $m06 = date('m',$nowts-(86400*150))."/1/".date('y',$nowts-(86400*150)); $m07 = date('m',$nowts-(86400*180))."/1/".date('y',$nowts-(86400*180)); $m08 = date('m',$nowts-(86400*210))."/1/".date('y',$nowts-(86400*210)); $m09 = date('m',$nowts-(86400*240))."/1/".date('y',$nowts-(86400*240)); $m10 = date('m',$nowts-(86400*270))."/1/".date('y',$nowts-(86400*270)); $m11 = date('m',$nowts-(86400*300))."/1/".date('y',$nowts-(86400*300)); $m12 = date('m',$nowts-(86400*330))."/1/".date('y',$nowts-(86400*330)); PROBLEM: all was fine for the last few months but several days back the 1st few months were wrong - like this... 03/1/09 02/1/09 12/1/08 * wrong 12/1/08 11/1/08 etc... * I think the math went wrong because FEB had 28 days - not 30 (not sure why just 1 month JANUARY was wrong...) I temporarily fixed it with less than 30 day jumps like: $m01 = date('m',$nowts-(0))."/1/".date('y',$nowts-(0)); $m02 = date('m',$nowts-(86400*28))."/1/".date('y',$nowts-(86400*28)); $m03 = date('m',$nowts-(86400*58))."/1/".date('y',$nowts-(86400*58)); $m04 = date('m',$nowts-(86400*88))."/1/".date('y',$nowts-(86400*88)); $m05 = date('m',$nowts-(86400*118))."/1/".date('y',$nowts-(86400*118)); $m06 = date('m',$nowts-(86400*150))."/1/".date('y',$nowts-(86400*150)); $m07 = date('m',$nowts-(86400*180))."/1/".date('y',$nowts-(86400*180)); Q: Any ideas how to fix this issue? (please try to keep it simple - 'cause I ain't no math wiz either) -- Thanks - RevDave Cool @ hosting4days . com [db-lists 09]
