为什么导出来的数据中文都是乱码??
下面是备份数据库的代码,但是为什么导出来的数据中文都是乱码??
// 备份数据库
define('IN_FDYU', true);
require('includes/config.php');
// 这里的账号、密码、名称都是从页面传过来的
if (!mysql_connect($db_host, $db_user, $db_pass)) // 连接mysql数据库
{
echo '数据库连接失败,请核对后再试';
exit;
}
if (!mysql_select_db($db_name)) // 是否存在该数据库
{
echo '不存在数据库:' . $db_name . ',请核对后再试';
exit;
}
mysql_query("set names 'utf8'");
$mysql = "set charset utf8;\r\n";
$q1 = mysql_query("show tables");
while ($t = mysql_fetch_array($q1))
{
$table = $t[0];
$q2 = mysql_query("show create table `$table`");
$sql = mysql_fetch_array($q2);
$mysql .= $sql['Create Table'] . ";\r\n";
$q3 = mysql_query("select * from `$table`");
while ($data = mysql_fetch_assoc($q3))
{
$keys = array_keys($data);
$keys = array_map('addslashes', $keys);
$keys = join('`,`', $keys);
$keys = "`" . $keys . "`";
$vals = array_values($data);
$vals = array_map('addslashes', $vals);
$vals = join("','", $vals);
$vals = "'" . $vals . "'";
$mysql .= "insert into `$table`($keys) values($vals);\r\n";
}
}
$filename = $db_name . "_" . date('Y-m-d',time()) . ".sql"; //存放路径,默认存放到项目最外层
$fp = fopen($filename, 'w');
fputs($fp, $mysql);
fclose($fp);
header('location:index.php');
?>
------解决思路----------------------
set names utf8
