面向对象风格
<?php/* Open a connection */$mysqli = new mysqli("localhost", "my_user", "my_password", "world");/* check connection */if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit();}/* Print current character set */$charset = $mysqli->character_set_name();printf ("Current character set is %s\n", $charset);$mysqli->close();?>
过程化风格
<?php/* Open a connection */$link = mysqli_connect("localhost", "my_user", "my_password", "world");/* check connection */if (!$link) { printf("Connect failed: %s\n", mysqli_connect_error()); exit();}/* Print current character set */$charset = mysqli_character_set_name($link);printf ("Current character set is %s\n",$charset);/* close connection */mysqli_close($link);?>
以上例程会输出：
Current character set is latin1_swedish_ci
