如何在PHP中的选定日期值中添加1年

Question

I am trying to add 1 year in selected date but I cannot get the output.

This is what I tried so far:

I am getting date from datepicker in textbox and store it in variable like the following:

$sdate = mysqli_real_escape_string($conn,$_POST['amc_date']);

I tried this code but it doesn't work.

$edate = date('d/m/Y', strtotime('+1 year', strtotime($sdate)));

Please help. Thanks.

Answer 1

$futureDate=date('Y-m-d',strtotime('+1 year'));

$futureDate is one year from now!

$futureDate=date('Y-m-d',strtotime('+1 year',strtotime($startDate)));

$futureDate is one year from $startDate!

Answer 2

You can use DateTime object for this.

// $sdate = '2018-04-02'
$sdate = mysqli_real_escape_string($conn,$_POST['amc_date']);
$dateTime = new \DateTime($sdate);
$resultDate = $dateTime->modify('+1 year')->format('d/m/Y');
// $resultDate = '02/04/2019'
