PHP 比较 date_diff 到时间流逝

Question

If I have

$time_interval = date_diff(date1, date2)

How can I do this in PHP?

If ($time_interval >= ('2 months and 15 days'))
    echo "time is '2 months and 15 days' or more"
else
    echo "time is less than '2 months and 15 days'"

I tried

if ($time_interval->m <= 2 and $time_interval->d < 15)

But this will return FALSE for 1 month and 20 days which is obviously wrong

Is there something like..?

$time_lapse = create_my_own_time_lapse(2months & 15 days)

Then it would be very neat to compare both

If ($time_interval >= $time_lapse)

SOLUTION

date_diff retuns a DateInterval object. I found the way to create my own DateInterval for '2 months and 15 days'. This is my updated code:

Visit PHP DateInterval manual for details

$today = new DateTime(date('Y-m-d'));
$another_day = new DateTime("2019-05-10");

$time_diff = date_diff($today, $another_day);

// 'P2M15D' is the interval_spec for '2 months and 15 days'
$time_interval = new DateInterval('P2M15D');

// Let's see our objects
print_r($time_diff);
print_r($timeInterval);

if($time_diff >= $time_interval)
    echo "<br/>time is '2 months and 15 days' or more";
else
    echo "<br/>time is less than '2 months and 15 days'";

Answer 1

your code is almost correct. Just remove the and and add strtotime()

from:

if ($time_interval >= ('2 months and 15 days'))
    echo "time is '2 months and 15 days' or more";
else
    echo "time is less than '2 months and 15 days'";

to:

if ($time_interval->getTimestamp()) >= strtotime('2 months 15 days'))
    echo "time is '2 months and 15 days' or more";
else
    echo "time is less than '2 months and 15 days'";

Answer 2

Easy way of doing this is converting your time to seconds and than compare these seconds with amount of seconds equal to 2 months and 15 days.

$timeInterval = strtotime('2009-12-01') - strtotime('2009-10-01');
$overSeconds = 60 * 60 * 24 * 75; // 60 seconds * 60 minutes * 24 hours * 75 days

if($timeInterval >= $overSeconds)
    echo "time is '2 months and 15 days' or more";
else
    echo "time is less than '2 months and 15 days'";
