How can sessions be used to ensure the retrieval of the last inserted ID in PHP?

When inserting data into a database in PHP, you can use sessions to store the last inserted ID. After inserting the data, you can retrieve the ID and store it in a session variable. This way, you can easily access the last inserted ID throughout the session without having to query the database again. 

// Start the session
session_start();

// Insert data into the database
// Example query: INSERT INTO table_name (column1, column2) VALUES (value1, value2)
// Assuming $last_insert_id contains the last inserted ID
$last_insert_id = mysqli_insert_id($connection);

// Store the last inserted ID in a session variable
$_SESSION['last_insert_id'] = $last_insert_id;

// Retrieve the last inserted ID from the session
$last_insert_id = $_SESSION['last_insert_id'];

// Now you can use $last_insert_id to access the last inserted ID throughout the session
