Content-Type: application/vnd.ms-excel">
    如果要将查询结果导出到Excel，只需将页面的Context-Type修改一下就可以了：
       header( "Content-Type: application/vnd.ms-excel">
    如果希望能够提供那个打开/保存的对话框，Content-Disposition参数，Content-Disposition参数本来是为了在客户端另存文件时提供一个建议的文件名，但是考虑到安全的原因，就从规范中去掉了这个参数
    Content-Disposition参数：
    attachment --- 作为附件下载   
    inline --- 在线打开
    具体使用如：header("Content-Disposition: inline; filename=文件名.mp3");
                Header("Content-Disposition：attachment;filename=test.xls");
    其实IE是根据Content-Disposition中filename这个段中文件名的后缀来识别这个文件类型的，所以，
    如果有很多种文件类型的时候，可以将Content-Type设置为二进制模式的：
                Header("Content-type:   application/octet-stream");
    示例：
    <?
    filename=′./download/d.rar′;filesize   =   filesize(filename);header("Content−Type:application/force−download");header("Content−Disposition:attachment;filename=".basename(filename));
    header( "Content-Length:   ".filesize);data   =   file_get_contents(filename);echodata;
    ?>
    这段代码的意识是打开页面后立即出现下载保存窗口，下载的文件为filename，摘取了常用的部分，其实还有其他一些mimetypes = array(
        'doc'        => 'application/msword',
        'bin'        => 'application/octet-stream',
