printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
/* print server version */
printf("Server version: %s\n", $mysqli->server_info);
/* close connection */
$mysqli->close();

过程化风格
<?php
$link = mysqli_connect("localhost", "my_user", "my_password");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
/* print server version */
printf("Server version: %s\n", mysqli_get_server_info($link));
