如何检查过去是否超过2天而不是将来？

Question

I want to check if the date is more that or equals 2 days in the past only , But it also works if it's in the future.

Here is the code:

$d = new DateTime('04-06-2018');

$todayDate = new DateTime();

$interval = $d->diff($todayDate);

$days = $interval->format('%a');

if($days >= 2)
{echo 'true'; }
else
{echo 'false';}

It returns true whenever the difference between the two dates is more that or equals 2 , How to solve that?

Answer 1

You can do this by checking invert property in your DateInterval .

$d = new DateTime('3-04-2018');
$todayDate = new DateTime();
$interval = $d->diff($todayDate);

if($interval->format('%a') >= 2
    && 0 === $interval->invert
) {
    echo 'true';
} else {
    echo 'false';
}

Answer 2

扩展是否检查日期是否为过去：

if($days >= 2 && strtotime($d) < time())

Answer 3

There is one more way to acheive this

return $interval->format("%r%a");

Cast to int if needed:

return (int)$interval->format("%r%a");

Here you will get positive and negative number to check future and past date.

Hope it helps
