"We need to fetch the data from the mysqli_result object that was returned to you when you executed your query using mysqli_query.Note: I removed the loop because with MAX query without any grouping you will get only 1 row returned. If you had multiple rows in result set you would need to loop through all of them"

We need to fetch the data from the mysqli_result object that was returned to you when you executed your query using mysqli_query.

    $max = "SELECT MAX(Id) as id FROM trialtabel2"; 
    $max1 =  mysqli_query($dblink, $max); 
    $row = mysqli_fetch_assoc($max1);    // this was missing
    $id=$row['id'];
    echo $id;

Note: I removed the loop because with MAX query without any grouping you will get only 1 row returned. If you had multiple rows in result set you would need to loop through all of them
