How can the MAX function be effectively used in conjunction with subqueries in PHP SQL statements to retrieve specific data?

When using subqueries in PHP SQL statements to retrieve specific data, the MAX function can be effectively used to find the maximum value within a set of results. This can be useful when you want to retrieve the highest value from a column in a subquery result set. By using the MAX function in conjunction with subqueries, you can easily extract the desired data without needing to manipulate the results further in your PHP code. 

$query = "SELECT column_name FROM table_name WHERE column_name = (SELECT MAX(column_name) FROM table_name)";
$result = mysqli_query($connection, $query);

if(mysqli_num_rows($result) > 0){
    while($row = mysqli_fetch_assoc($result)){
        echo $row['column_name'];
    }
}
