本文实例讲述了php获取给定日期相差天数的方法。分享给大家供大家参考,具体如下:
方法一:
<?php function count_days($a,$b){ $a_dt=getdate($a); $b_dt=getdate($b); $a_new=mktime(12,0,0,$a_dt['mon'],$a_dt['mday'],$a_dt['year']); $b_new=mktime(12,0,0,$b_dt['mon'],$b_dt['mday'],$b_dt['year']); return round(abs($a_new-$b_new)/86400); } //今天与2017年8月26日相差多少天 $date1=strtotime(date("Y-m-d")); $date2=strtotime('2017-8-26'); $result=count_days($date1,$date2); echo $result; ?>
运行结果:187
方法二:
<?php //今天与2017年8月26日相差多少天 $Date_1=date("Y-m-d"); $Date_2="2017-8-26"; $d1=strtotime($Date_1); $d2=strtotime($Date_2); $Days=round(($d2-$d1)/3600/24); echo "今天与2017年8月26日相差".$Days."天"; ?>
运行结果:
今天与2017年8月26日相差187天
