### 范例

Example #1 面向对象风格

    <?php
    /* Open a connection */
    $maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");

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

    /* Print current character set */
    $charset = $maxdb->character_set_name();
    printf ("Current character set is %s\n", $charset);

    $maxdb->close();
    ?>

Example #2 过程化风格

    <?php
    $link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");

    /* check connection */
    if (!$link) {
       printf("Connect failed: %s\n", maxdb_connect_error());
       exit();
    }

    /* Print current character set */
    $charset = maxdb_character_set_name($link);
    printf ("Current character set is %s\n",$charset);

    /* close connection */
    maxdb_close($link);
    ?>

以上例程的输出类似于：

    Current character set is ascii
