You can use a function with your array and the $user you want to count as parameter, and then loop into the array and sum +1 for each interaction that matches your prerequisites.

Assuming your parent array is named $users , you can do the following:

function countConsecutive($users, $username)
{
    $total = 0;

    foreach($users as $user) {
        if($user['user'] === $username && $user['time'] >= date('Y-m-d H:i:s', strtotime('-10 minutes'))) {
            $total++;
        }
    }

    return $total;
}

The return of the function will be the count of consecutive date-time from the user in the last 10 minutes.
