Might save someone some time...

<?php
$prototype
='Rows matched: 0 Changed: 1 Warnings: 2';
list(
$matched, $changed, $warnings) = sscanf($prototype, "Rows matched: %d Changed: %d Warnings: %d");
?>

If inserted just one row, mysqli_info() returns empty string which might be confusing, but mysqli_affected_rows() returns 1 in this case.
