PHP Date distance How many days

Meet a demand, to calculate the day after the start of the activity ~

Scenario One: Date_diff () function, but requires PHP version 5.3+

$date 1=date_create ("2015-11-02"));$date 2=date_create (Date(' y-m-d ', Time()));$diff=date_diff ($date 1,$date 2);$has _start=$diff->days + 1;Echo $count _day= 10000 *POW($has _start, 2);Var_dump($diff);//Echo $diff->format ("%r%a days");

Scenario Two: Strtotime (), all versions available, but 2035 is a hurdle, int type overflow problem

$start _day= "2015-11-04";$cur _day=Date(' y-m-d ', Time());$start _time=Strtotime($start _day);$cur _time=Strtotime($cur _day);$diff=$cur _time-$start _time;$diff _day=Ceil($diff/3600/24) + 1;$d=Ceil($diff/3600/24);$h=Ceil($diff% (3600/24)/3600);$m=Ceil($diff% (3600/24)/60);Echo"Difference$d days $h hours $m minutes";
