adding days in date and difference between two days

we can add days in date time very easily.

lets we have a date $date =”2010-06-04 12:45″ . we want to add some days with it.

lets the day is $days = 90;

so adding day into date fast we need to convert date in millisecond. we can do this easily by a php function strtotime();

so we can write $date = strtotime(“2010-06-04 12:45″);

then we can use this function to add a date.

$addeddate= date(“Y-m-d H:i:s”, $date+((60*60)*24*$days));

it will return 2010-11-11 12:45:50 .

that’s it. we can difference between two days that way also.

there is another way but it take only y-m-d .

function dateDiff($dformat, $endDate, $beginDate)
{
$date_parts1=explode($dformat, $beginDate);
$date_parts2=explode($dformat, $endDate);

$start_date=gregoriantojd($date_parts1[1], $date_parts1[2], $date_parts1[0]);
$end_date=gregoriantojd($date_parts2[1], $date_parts2[2], $date_parts2[0]);

return $end_date – $start_date;
}

$currentTime=date(‘Y-m-d’);

$date =”2010-06-04 12:45″;

$end = date(‘Y-m-d’, strtotime($date));

this will convert date in to this
if date = “2010-06-04″;

the call the function

$dif=dateDiff(“-”, $end,  $currentTime);

if out date format is 2010/06/04 then

we call it this way $diff =dateDiff(“/”,$end,$currentTime);
