使用php检查从今天起超过30天的特定日期

Question

我尝试使用格式Ymd找出今天日期与特定日期之间的差异。 如何检查特定日期是否从今天起超过30天？

例如：

$date1 = '20160315'; // 2016-03-15
$date2 = '20160115'; // 2016-01-15

Answer 1

试试这个

$date1=date_create('20160315');
$date2=date_create('20160115');
$diff=date_diff($date1,$date2);
$days = $diff->format("%a");

if($days > 30) do something

Answer 2

这么简单......

$date1 = '20160315'; // 2016-03-15
$date2 = date(Ymd); // 2016-01-15

$day_difference = $date1  - $date2 
if($day_difference > 30) {
 echo 'specific day is greater than 30 days from today';
} else {
 echo 'specific day is less than 30 days from today';
}

Answer 3

试试这个：

$datetime1 = new DateTime('2009-10-11');
$datetime2 = new DateTime('2009-11-13');
$interval = $datetime1->diff($datetime2);
$int = $interval->format('%R%a');

if($int > +30) {
    echo "Greater than 30 days";
} else {
    echo "Less than 30 days";

}
