一个利用header()函数来实例简单的文件下载,我们简单的讲解了excel的操作教程,有需要的朋友可以参考一下,代码如下:

1. header("Content-type:application/vnd.ms-excel"); 
2. header("Content-Disposition:attachment;filename=test_data.xls"); 

实例代码如下:

1. $filename = "20090210.xls"; 
2. $file = fopen(PUBLIC_EXPORT_DIR.$filename,"r"); // 打开文件 
3. Header("Content-type:application/force-download");   
4. Header("Accept-Ranges:bytes");    
5. header("Content-Type: application/msexcel"); 
6. Header("Accept-Length:".filesize(PUBLIC_EXPORT_DIR.$filename));    
7. Header("Content-Disposition:attachment;filename=".$filename);    
8. echo fread($file,filesize(PUBLIC_EXPORT_DIR.$filename)); 
9. fclose($file);
