如何在php中将日期时间的第一个对象与另一个日期时间对象进行比较

Question

here I am using one date time object is this

 $cdate  = date('d/m/Y h:i:sa')  

and another date time object is this

$udate = date("d/m/Y h:i:sa", strtotime("72 hours"));

for comparing I am using this condition

 if($cdate >= $udate)

but problem is this...in this case its only comparing only day not entire date and time.

Answer 1

The strings returned from date() are only comparable in certain circumstances. You should use DateTime() whose objects are always comparable:

$cdate  = new DateTime();
$udate = new DateTime('+3 days');
if($cdate >= $udate) {

}
