How can PHP developers ensure that data is correctly ordered numerically when retrieved from a database table?

When retrieving data from a database table in PHP, developers can ensure that the data is correctly ordered numerically by using the ORDER BY clause in their SQL query. By specifying the column containing numerical data in the ORDER BY clause, the retrieved data will be sorted in ascending or descending order based on that column. 

// Connect to the database
$connection = new mysqli('localhost', 'username', 'password', 'database_name');

// Query to retrieve data ordered numerically
$query = "SELECT * FROM table_name ORDER BY numerical_column ASC";

// Execute the query
$result = $connection->query($query);

// Fetch and display the data
while ($row = $result->fetch_assoc()) {
    echo $row['numerical_column'] . "<br>";
}

// Close the connection
$connection->close();
