/* check connection */
if (mysqli_connect_errno()) {
    
printf("Connect failed: %s\n"mysqli_connect_error());
    exit();
}

/* determine our thread id */
$thread_id $mysqli->thread_id;

/* Kill connection */
$mysqli->kill($thread_id);

/* This should produce an error */
if (!$mysqli->query("CREATE TABLE myCity LIKE City")) {
    
printf("Error: %s\n"$mysqli->error);
    exit;
}

/* close connection */
$mysqli->close();
?>

Example #2 Procedural style

printf("Connect failed: %s\n"mysqli_connect_error());
    exit();
}

/* determine our thread id */
$thread_id mysqli_thread_id($link);

/* Kill connection */
mysqli_kill($link$thread_id);

/* This should produce an error */
if (!mysqli_query($link"CREATE TABLE myCity LIKE City")) {
    
printf("Error: %s\n"mysqli_error($link));
