In this case, why cannot I download files?

In this case, why cannot I download files? $ Root = "D:/wamp/www/New Folder /";
If (is_dir ($ root ))
{
$ OpenHandle = opendir ($ root );
While (false! ==( $ File = readdir ($ openHandle )))
{
If (! Is_dir ($ root. $ file ))
{
Echo "". $ file ."
";
Echo "$ root $ file
";
}
}
Closedir ($ openHandle );
}
Else
{
Echo "the folder does not exist ";
}
?>
Why can't this code be used to download files? the Sogou browser has tried IE.

If ($ do = 'low'), this judgment is always unsuccessful. what should I do if the code in the braces cannot be executed?

Is there a problem with your statement? "echo" ". $ root. $ file ."
";" How to change it?

Href = '? Do to href = 'A. php? Do

A. is php yours? Php file name

Are you tested in LINUX? files downloaded from LINUX cannot be successfully executed on WINDOWS. some messy content will be written for support.
