在2004-01-08再加上15天 = 2004-01-23


$years = date("Y"); //用date()函式取得目前年份格式0000
$months = date("m"); //用date()函式取得目前月份格式00
$days = date("d"); //用date()函式取得目前日期格式00
$day = date("Y-m-d",mktime(0,0,0,$months,$days+15,$years));


在2004-01-08再加上6個月 = 2004-07-08

$years = date("Y"); //用date()函式取得目前年份格式0000
$months = date("m"); //用date()函式取得目前月份格式00
$days = date("d"); //用date()函式取得目前日期格式00
$day = date("Y-m-d",mktime(0,0,0,$months+6,$days,$years));


在2004-01-08再加上2年 = 2006-01-08

$years = date("Y"); //用date()函式取得目前年份格式0000
$months = date("m"); //用date()函式取得目前月份格式00
$days = date("d"); //用date()函式取得目前日期格式00
$day = date("Y-m-d",mktime(0,0,0,$months,$days,$years+2));


在2004-01-08再減15天 = 2003-12-24

$years = date("Y"); //用date()函式取得目前年份格式0000
$months = date("m"); //用date()函式取得目前月份格式00
$days = date("d"); //用date()函式取得目前日期格式00
$day = date("Y-m-d",mktime(0,0,0,$months,$days-15,$years));


在2004-01-08再減6個月 = 2003-07-08

$years = date("Y"); //用date()函式取得目前年份格式0000
$months = date("m"); //用date()函式取得目前月份格式00
$days = date("d"); //用date()函式取得目前日期格式00
$day = date("Y-m-d",mktime(0,0,0,$months-6,$days,$years));


在2004-01-08再減2年 = 2002-01-08

$years = date("Y"); //用date()函式取得目前年份格式0000
$months = date("m"); //用date()函式取得目前月份格式00
$days = date("d"); //用date()函式取得目前日期格式00
$day = date("Y-m-d",mktime(0,0,0,$months,$days,$years-2));
