$filename='文件名称';
$filetitle='你的标题';

// PHP文件句柄，php://output 表示直接输出到浏览器

}

// 计数器
$cnt = 0;
// 每隔$limit行，刷新一下输出buffer，节约资源
$limit = 100000;
// 逐行取出数据，节约内存
while ($res = mysql_fetch_assoc($query)) {
$cnt ++;
if ($limit == $cnt) { //刷新一下输出buffer，防止由于数据过多造成问题
ob_flush();
flush();
$cnt = 0;
}
echo trim($res['id']). "\t";
echo "\n";
}
}第二种方法：
