Comparing objects of DateTime in php is not working

I am making an API in which I need to check the token validity for a particular user and for that I am using DateTime function of php. I am saving a token and current time on login and I want token to be valid for 10 minutes, so when a user makes a request within first 10 minutes of its login I want to update the time validity of token. 

$currentTime = new DateTime();
$curTime = $currentTime->format("Y-m-d H:i:s");
$time10MinutesAgo = new DateTime("10 minutes ago");
$time10Minutes = $time10MinutesAgo->format("Y-m-d H:i:s");
$token_time = $query1_r['token_time']; // value is stored in the db(mysql)
if (($curTime > $token_time) && ($token_time >= $time10Minutes)){}

first I was unable to pass the second condition but now even my page is not working.

If you already have DateTime object, don't convert them to strings, just compare objects between each other, like this:

$currentTime = new DateTime();
$time10MinutesAgo = new DateTime("10 minutes ago");
$tokenTime = new DateTime($query1_r['token_time']);

if ($time10MinutesAgo <= $tokenTime && $tokenTime <= $currentTime) {
    echo "Token time is between now and now-10 minutes.";
}

Use epoch time values for time comparisons it's much easier to compare numbers instead of dates.

$currentTime = time();
$time10MinutesAgo = strtotime('-10 minutes');
$token_time = strtotime($query1_r['token_time']); // value is stored in the db(mysql)
if(($currentTime >$token_time) && ($token_time >= $time10MinutesAgo )){}
