How can the use of mysqli vs. mysql functions impact the retrieval of last insert ID in PHP?

When using mysqli functions instead of mysql functions in PHP, the method to retrieve the last insert ID changes. With mysqli, you can use the mysqli_insert_id() function to get the ID of the last inserted record, while with mysql, you would use the mysql_insert_id() function. It's important to use the correct function corresponding to the database extension being used to ensure the retrieval of the last insert ID works correctly. 

// Using mysqli functions to retrieve last insert ID
$mysqli = new mysqli("localhost", "username", "password", "database");

// Perform insert query
$mysqli->query("INSERT INTO table_name (column_name) VALUES ('value')");

// Get last insert ID
$last_id = $mysqli->insert_id;

echo "Last Insert ID: " . $last_id;
