 //在conf/php.ini中,在vim用"/php_mysql"搜索到extension=php_mysql.dll,去掉前面的";",同时在下面增加extension=php_mysqli.dll;
$mysqli = new mysqli("127.0.0.1","用户名", 密码","库名");
$query="select * from  表 order by theindex desc";
$mysqli->query("SET NAMES gb2312");//注意此处不加会乱码
$result = $mysqli->query($query);

 //printf() 函数输出格式化的字符串
while(list($name, $theindex) = $result->fetch_row())
        echo("
".$name.$theindex);

$con = mysql_connect("localhost", "用户名", "密码");
if ($con) {
        mysql_query("set names 'gb2312'");
        mysql_select_db("库名", $con);//注意此处不加会乱码
                                $rs = mysql_query("select * from  表 order by theindex desc;", $con);
                                if ($rs) {
                                  echo ("

");
                                        while($row = mysql_fetch_assoc($rs))
                                        {
                                                echo "" .

$row[name]
