The month difference between two time instance codes:

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

Example 2

Code to copy code as follows
<?php
\$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

Code to copy code as follows
<? Php

/*
*
* (www.111cn.net) 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 "<br>";
echo getchabetweentwodate (' 2010-08-16 ', ' 2010-08-11 ');
?>

Example 4

Code to copy code as follows
<?php
\$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. " Day <br> ";
echo \$hour. " Hours <br> ";
echo \$minute. " Minutes <br> ";
echo \$second. " Seconds <br> ";
?>

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