How to compare if the difference of 2 times is greater than 2 hours

I have to compare if result from a subtraction is greater on less than 2 hours. I don't know how exactly do make this comparison. I tried the following. It is correct for the third if, but for the first and second result is not correct.

Here's my view:

 <?php
    $transport= new DateTime($row->transportDate);
    $max=new DateTime(max($forecast_array));
    $interval = $transport->diff($max);

    if($max->format('Y-m-d H:i:s') < $transport->format('Y-m-d H:i:s') && $interval->format('%h:%i:%s') >= '2:00:00' ) {     
     
    echo '<img src="<?= base_url();?>/assets/images/tick.png">';
     } 
     if($max->format('Y-m-d H:i:s') < $transport->format('Y-m-d H:i:s') && $interval->format('%h:%i:%s') < '2:00:00' ) {    
     
   echo '<img src="<?= base_url();?>/assets/images/warning.png">';
    }
     if($max->format('Y-m-d H:i:s') > $transport->format('Y-m-d H:i:s')) { 
    
    echo '<img src="<?= base_url();?>/assets/images/forbidden.png">';
      } ?>
Edited: Now, I'm using this code: Is it correct?

<?php
$transport = strtotime($row->transportDate); 
$max = strtotime(max($forecast_array));
$interval = abs($max - $transport); 

if($max < $transport &&  $interval >= 2 * 60 * 60 ) {     
                       
   echo '<img src="<?= base_url();?>/assets/images/tick.png">';
}

 $transport= new DateTime($row->transportDate);
 $max=new DateTime(max($forecast_array));
 $interval = $transport->diff($max);

 if ($interval->h > 2) {
     //
 }

To compare date/time differences as simple as your example, I'd suggest to not use the DateTime() class, but use simple timestamps. E.g.:

$transport = strtotime($row->transportDate); // strtotime parses the time if it is not a timestamp, if it already is just use as is, i.e. without strtotime()
$max = strtotime(max($forecast_array));
$intervall = abs($max - $transport); 
// $intervall is now the difference in seconds therefore you can do this simple check:
if($interval >= 2 * 60 * 60){ // 2 hours à 60 minutes à 60 seconds
    // interval > 2 hours
} else {
    //...
}
