What are some alternative methods or best practices for handling auto-incremented ID values in PHP when inserting records into a database?

When inserting records into a database in PHP, it is common practice to use auto-incremented ID values as primary keys. One alternative method is to use the `LAST_INSERT_ID()` function provided by MySQL to retrieve the last inserted ID after an INSERT query. This ensures that the correct ID value is used when inserting related records into other tables. 

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

// Insert a record into the table
$query = "INSERT INTO table_name (column1, column2) VALUES ('value1', 'value2')";
$connection->query($query);

// Get the last inserted ID
$last_id = $connection->insert_id;

// Use the last inserted ID for further operations
$query2 = "INSERT INTO related_table (id, column3) VALUES ('$last_id', 'value3')";
$connection->query($query2);

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