去掉 abs
返回 -11 表示 2013-02-01 比 2014-01-01 少 11 个月
当然你也可以将整个返回值 abs,但这样就只是知道差 11 个月,但不知道是多了还是少了
function getMonthNum($date1,$date2){ $date1_stamp=strtotime($date1); $date2_stamp=strtotime($date2); list($date_1['y'],$date_1['m'])=explode("-",date('Y-m',$date1_stamp)); list($date_2['y'],$date_2['m'])=explode("-",date('Y-m',$date2_stamp)); return abs($date_1['y']-$date_2['y'])*12 +$date_2['m']-$date_1['m']; } echo getMonthNum("2013-02-01","2014-01-01");echo getMonthNum("20130201","20140101");echo getMonthNum("201302","201401");
=$date2[0]){ return abs($date1[0] - $date2[0]) * 12 + abs($date1[1] - $date2[1]); } else{ return abs($date2[0] - $date1[0]) * 12 - abs($date1[1] - $date2[1]); } }echo getMonthNum("2013-02-01","2014-01-01",'-');?>
上面写错了。。。。。重发:
function getMonthNum($date1,$date2){ $date1_stamp=strtotime($date1); $date2_stamp=strtotime($date2); list($date_1['y'],$date_1['m'])=explode("-",date('Y-m',$date1_stamp)); list($date_2['y'],$date_2['m'])=explode("-",date('Y-m',$date2_stamp)); return abs(($date_2['y']-$date_1['y'])*12 +$date_2['m']-$date_1['m']); } echo getMonthNum("2013-02-01","2014-01-01");echo getMonthNum("20130201","20140101");echo getMonthNum("201302","201401");
function getMonthNum($date1,$date2){ $date1_stamp=strtotime($date1); $date2_stamp=strtotime($date2); list($date_1['y'],$date_1['m'])=explode("-",date('Y-m',$date1_stamp)); list($date_2['y'],$date_2['m'])=explode("-",date('Y-m',$date2_stamp)); return abs($date_1['y']-$date_2['y'])*12 +$date_2['m']-$date_1['m']; } echo getMonthNum("2013-02-01","2014-01-01");echo getMonthNum("20130201","20140101");echo getMonthNum("201302","201401");echo getMonthNum("2013-02-01","2012-01-01");//11
