"); } else { printf ("Error: %s ", $mysqli->error); } /* close connection */ $mysqli->close(); ?> Procedural style <?php $link = mysqli_connect("localhost", "my_user", "my_password", "world"); /* check connection */ if (mysqli_connect_errno()) { printf("Connect failed: %s ", mysqli_connect_error()); exit(); } /* check if server is alive */ if (mysqli_ping($link)) { printf ("Our connection is ok!
