How to compare the different between two dateTime

[bennos89]

Hi,

I have datetime in my database and I want to check against the current datetime. I want to display the different between them. and If my database expiry. The php show not show the datetime.

$d1=new DateTime($c[0][0][4]);
$d2=new DateTime();
$diff=$d1->diff($d2);

However, I am getting weird number the sum wont tally.
echo $diff->format('%d-%m-%y %h:%i:%s');

What is the different between diff and sub

First if you are putting it in DB make it in UNIX time format is (1234454564) and for example you take current time also in UNIX and than compare it.

$time_in_db = //time in UNIX from DB;
$current = time();


if( $current < $time_in_db ){

//do something
}
else{
//report error
}
