PHP calculates the difference of two times (second time of Day of the month year) _php tutorial

PHP calculates the difference of two times (second time of day of the month)

The month difference between two time instance codes:

The code is as follows
$yourdate = "2012-10-20"; $yourdate _unix=strtotime ($yourdate); Echo (Date ("Y", $yourdate _unix)-date ("Y")) *12+ (date ("M", $yourdate _unix)-date ("M"));

Example 1

code as follows
/* * Calculates the month difference for 2 time periods * @param $st start time $et end time (timestamp format) * @return $total return Difference */ function Getmonthnum ($st, $et) { $s _m = date (' n ', $st), $e _m = Date (' n ', $et), $s _y = date (' y ', $st); $e _y = d Ate (' Y ', $et); $total = 13-$s _m + ($e _y-$s _y-1) * + $e _m;//Calculate month difference return $total; }

Example 2

The code is as follows

$one = Strtotime (' 2011-05-08 07:02:40 ');//Start time timestamp $tow = Strtotime (' 2012-12-25 00:00:00 ');//End time Timestamp $cle = $tow-$one; The time stamp difference value is obtained /* This is just a hint echo ceil ($cle/60); How many minutes. echo ceil ($cle/3600); How many hours? Echo ceil ($cle/3600/24); How many days */ /*ceil () function, that is, into a method to take the whole * * $d = cell ($cle/3600/24); $h = cell (($cle% (3600*24))/3600); % take-up $m = cell (($cle% (3600*24))/60); echo "Two time difference $d days $h hours $m minutes" ?>

Example 3

The code is as follows

/* * * Function function: Calculates two dates in YYYY-MM-DD format, a few days apart * */ function Getchabetweentwodate ($date 1, $date 2) { $Date _list_a1=explode ("-", $date 1); $Date _list_a2=explode ("-", $date 2); $d 1=mktime (0,0,0, $Date _list_a1[1], $Date _list_a1[2], $Date _list_a1[0]); $d 2=mktime (0,0,0, $Date _list_a2[1], $Date _list_a2[2], $Date _list_a2[0]); $Days =round (($d 1-$d 2)/3600/24); return $Days; } echo getchabetweentwodate (' 2010-08-11 ', ' 2010-08-16 '); echo " "; echo getchabetweentwodate (' 2010-08-16 ', ' 2010-08-11 '); ?>

Example 4

code as follows

$startdate = "2010-12-11 11:40:00″; $enddate = "2012-12-12 11:45:09″; $date =floor ((Strtotime ($enddate)-strtotime ($startdate))/86400); $hour =floor ((Strtotime ($enddate)-strtotime ($startdate))%86400/3600); $minute =floor ((Strtotime ($enddate)-strtotime ($startdate))%86400/60); $second =floor ((Strtotime ($enddate)-strtotime ($startdate))%86400%60); echo $date. " Days ”; echo $hour. " Hours ”; echo $minute. " Minutes ”; echo $second. " Seconds ”; ?>

Example four is my favorite one can be calculated to days and hours of the second Oh, of course, the specific need to be based on their own needs.
