It should be noted that using mysqli_stmt->insert_id will not result in a unique ID being returned for each execution of a prepared insert statement.  In practice, it appears that the first insertion ID is returned.  If you are performing multiple inserts with the same prepared statement (one invocation of mysqli_stmt::prepare and multiple invocations of mysqli_stmt::execute() for a given statement), and need to keep the unique ID for each insert, use mysqli_connection->insert_id.

This can be used as a property of a statement as well:

<?php

$statement = $mysqli->prepare($query);

echo $statement->insert_id;

?>
