从mysql调出来的数据在php页面显示乱码 急急急.....

require_once('common.php');   

$countRow = mysql_num_rows(mysql_query("SELECT count(*) FROM gb_content"), MYSQL_BOTH);    //这样求总行数

$count = $countRow[0]; //总行数   

$_GET['page'] = intval($_GET['page']);   

if ($_GET['page']<=0) {   

    $_GET['page'] = 1;   

}   

  

$lines = 10; // 每页行数   

$page = $_GET['page'];// 当前页   

$limit = ($page - 1) * $lines;//起启行   

$total = ceil($count/$lines); // 总页数  





mysql_query("set names 'utf8'");//加上这句试试



$result = mysql_query("SELECT * FROM gb_content order by id desc limit " .$limit. ','.$lines.'');//查询数据



while ($row = mysql_fetch_array($result, MYSQL_BOTH)) {// 取一条数据
