Are there any best practices for efficiently working with auto_incremented IDs in PHP and MySQL?

When working with auto_incremented IDs in PHP and MySQL, it is important to efficiently handle the generation and retrieval of these IDs. One best practice is to use the MySQL function LAST_INSERT_ID() to retrieve the last auto_incremented ID generated during an INSERT operation. This ensures that you are always working with the correct ID without having to query the database again. 

// Insert data into the database
$query = "INSERT INTO table_name (column1, column2) VALUES ('value1', 'value2')";
$result = mysqli_query($connection, $query);

// Retrieve the last auto_incremented ID generated
$id = mysqli_insert_id($connection);

// Use the ID for further operations
echo "The new ID is: " . $id;
