Add days to current date from MySQL with PHP

问题

I have a fixed date from MySql

startDate = 07/03/2011

I wanted to add 60 days on top this date to have an endDate.

$startDate = $result['startDate'];
$endDate = ??? + strtotime("+60 days");
echo $endDate;

From my research, I know it has something do with strtotime, but all the sites I come across with based the start date from current workstation's time. My date is already fixed and entered prior to running and getting the endDate.

Help? Thanks in advance!

回答1:

In addition to PHP solutions others are providing, you can create the endDate right inside of MySQL and save yourself some of the trouble:

SELECT startDate, DATE_ADD(startDate, INTERVAL 60 DAY) AS endDate FROM table;

-- Or by months (not exactly the same thing)
SELECT startDate, DATE_ADD(startDate, INTERVAL 2 MONTH) AS endDate FROM table;

Relevant documentation here...

You could reformat the results of strtotime()

$startDate = $result['startDate']; // 07/03/2011
$endDate = date("m/d/Y", strtotime("$startDate +60 days"));

$startDate = "07/03/2011";
$endDate = strtotime("+60 days",time($startDate));
$formatted = date('m/d/Y',$endDate);
echo $endDate . "<br/>" . $formatted;

86400 seconds in a day, times number of days.. and add it to current time.

$nextMonth = time()+86400*60;
echo date("Y-m-d H:i:s", $nextMonth);
