Generate expiry date in PHP

Question

I'm trying to generate a list of medicine those are going to be expired in next three month. In the database, I have stored expiry date in the format of MM YYYY. I'm new to PHP, can somebody help me with idea how to achieve this goal

Php code

$NintyDays = date('Y-m-d', strtotime('+90 days')); 
$dbDate = '2018-12-20';
 if (strtotime($dbDate) <= strtotime($NintyDays ))
 {
 // some other code 
}

Answer 1

您可以通过 sql 查询来完成：

mysql_query("SELECT * FROM medicine_table m WHERE m.expiry < (NOW() + INTERVAL 3 MONTH)");

Answer 2

I also advise MySQL solution as above if it can be used.

if you need PHP solution it could be like this:

$expDate = new DateTime('2018-12-20');
$threeMonths = new DateTime();
$threeMonths->add(new DateInterval('P3M'));

if ($expDate < $threeMonths) {
   // code
}
