That works fine for html/php files. But it doesn't work for images,
pdf's, etc.
And the original op indicated he didn't want to put a PHP file in every
directory, and wanted to protect all file types.
When the "all file type" requirement comes up and the customer doesn't
wish to use http authentication, I use a combination of .htaccess and
PHP. When someone request access to a protected file, Apache redirects
to a PHP script which checks the credentials. If they are logged in, it
retrieves the file (from a directory outside the webserver's document
root directory, applies the appropriate content-type header and delivers
it. If they aren't logged in yet, I present the login screen, and after
logging in, they are presented with the file.
They can also bookmark these pages.
