单击文件链接时未获得“保存/打开文件”对话框

I'm creating html links to files on my server, however when I click the links I do not get a popup window asking for Save or download dialog like this one:

I want to get that window when i click on the links.

Here's the code I'm using:

<?php
listDirectory(".");

function listDirectory($path) 
{     

$handle = @opendir($path);   

 while (false !== ($file = readdir($handle)))

 {         

 if ($file == '.' || $file == '..') continue;  
 if ( is_dir("$path/$file")) 
 {  
print ("<a href=\"$path/$file\">$path/$file</a>");   
 }  
 else  
 {  
print ("<a href=\"$path/$file\">$path/$file</a>"); 
  }     
  }     
 closedir($handle); 
  }
?> 

Note: print ("$path/$file"); ~ works only for particular browser only ( not for IE ) and Directory download cannot be done

If you do not need to support old Browsers, you can use the HTML5 download attribute.

If support for non-HTML5-Browsers is needed, you can use PHP to force the browser to download the file using a custom set header:

Content-disposition: attachment; filename=my_file.extension
Content-Type: application/octet-stream

Sending the application/octet-stream content type doesn't allow the browser to display the document (e.g., if it is an iname or something else the browser can display itself).
