header("Content-type:application/vnd.ms-excel");
header("Content-Disposition:attachment; filename=使用者資訊表.xls");
require_once('./class.db.php');
$db = new DB('localhost', 'app_vmovies', 'root', '123456');
$sql = 'select * from `user` order by `id` desc';
$ret = $db->get_results($sql);
 
// 輸出內容如下：   
echo "ID"."t";
echo "暱稱"."t";
echo "性別"."t";
echo "OpenId"."t";
echo "平臺"."t";
echo "註冊日期"."t";
echo "n";
 
$len = count($ret);
for ( $i = 0; $i < $len; $i++ ) {
    echo $ret[$i]["id"]."t";
    echo $ret[$i]["nickname"]."t";
    echo $ret[$i]["gender"]."t";
    echo $ret[$i]["openid"]."t";
    echo $ret[$i]["pf"]."t";
    echo $ret[$i]["regdate"]."t";
    echo "n";
}

3.另word格式匯入類似，，指定header就可以了：

header("Content-Type:   application/msword");       
header("Content-Disposition:   attachment;   filename=doc.doc");
