What are some best practices for ensuring data is inserted at the end of a table in PHP?

When inserting data into a table in PHP, it is important to ensure that the data is inserted at the end of the table to maintain the integrity of the data. One way to achieve this is by using the "ORDER BY" clause in the SQL query to order the data by a unique identifier in descending order and then selecting the first row. This will ensure that the new data is inserted at the end of the table. 

<?php
// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Insert data at the end of the table
$sql = "INSERT INTO table_name (column1, column2) VALUES ('value1', 'value2') ORDER BY unique_id DESC LIMIT 1";
if ($conn->query($sql) === TRUE) {
    echo "Data inserted successfully at the end of the table";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}

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