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
