That would be very slow and prone to failure. What happens when Apache
comes across a binary file that contains ?php inside? It seems
unlikely, but I've found the more unlikely something should be, the more
often it occurs at just the wrong moment! For example, a document that
talks about PHP, or an image that randomly contains those characters as
part of the bitmap data?

Also, the idea of tying an ID into the DB does still allow you to use
friendly URLs, but is the ability to guess filenames really something
you want in a security system? It would be more prone to brute force
attacking I think.

 all files (web pages, pictures, and exe files) and folders in a directory
 should be protected against anonymous users.
 I create an application with php and mysql for registered users. when a user
 registers it's information will be saved in database and its username and
 password will be added to .htpass file. so registered users can reach
 protected area.
 But browser prompts login dialog, when users want to access this folder. How
 can I run login process with php.
 Thanks

  it sounds as if apache - or whatever your http server is - is not aware of
  your php script.  All apache knows is that someone is trying to access a
  directory or file that is protected, it does not know that it should send
  that request to the php script for a login.
 
  What are the protected resources that you want a login for?

The two login processes are separate from each other. The .htaccess
method is handled by Apache, completely apart from PHP. I believe it is
possible, but is unreliable because of the way different browser/server
combinations behave.

Your best bet is to store these files outside of web route, and access
them with a URL like this:

file.php?id=123456

your web route might be something like /var/www/html/yoursite
(where /var/www/html is the web root)
your documents and secure files could be at /var/www/files/yoursite

In your DB, the file id 123456 maps to a specific file on the hosting.
This file isn't accessible from the web normally, so PHP will have to
use something like fpassthru() to open dump the contents to the browser
(obviously sending the correct header() mime type, etc). The advantage
to this is you can use your PHP login system, and check each file
download attempt against the session to ensure they are a valid user who
should be able to access this file. Also, the obfuscation of the
filename means that someone is less likely to guess at a filename. The
id itself can be anything from a hash of the filename to an auto
increment id in the DB.
