My very basic code is:
$fname='alpha.ext';
readfile($fname);
?>
Only when ext is txt I'm getting a reasonable content, otherwise there's a
lot of bush. What function should I use to open doc, xls, pdf, gif?...
Can you help to a supernewbie???

This has nothing to do with the extension. It is the contents of the
files.
If you renamed alpha.ext to alpha.doc, the output would still be the
same.
In general, a .doc file will be written by Microsoft Word in its
custom format, similarly for all the other files.
A .gif file is a binary representation of an image. If you send the
correct headers, then the results of the readfile with a .gif file
would be an image on your browser.

If what you want to do is sending a gif, jpeg, pdf file or whatever
file to the browser and the browser displays it as it would if you had
clicked on a direct link to the file, then you must send the mime type
of the file in the HTTP response:
header("Content-Type: image/gif");
for a gif file, for example.
With direct links, the web server does it automatically, but if you
want to do it in PHP, you have to do it yourself. Read the user
comments on http://www.php.net/readfile to see some examples.

It's working good with this header function, it displays O. K. There is
another question (I'm probably stubborn): the address line shows something
like http://www.xxx/vvv/alpha.pdf. And this is my problem - can I "force"
system (server, browser?) to keep showing http://......something.php ? The
true reason for this is, that in my PHP script I put the code that redirects
unlogged user to somewhere. But when you remember once only the address
http://......./alpha.pdf you will reach it any time without logging. Sorry,
I'm not sure if it's clear enough...

It is doing exactly what you asked. Use used the header() function to
redirect to a different page. The browser requested the new page and
displayed its url. If you redirect, that's how it works.
And even if the browser didn't display the URL your files would not be
secure. Security by obfustication is worse than no security - at least
with no security, you know you're insecure.
If you want to protect them from being downloaded, you need to either
use HTTP authentication or deliver the files in your script (with the
appropriate headers).

you can use sessions to check if the user is authorized (eg logged in or whatever) to view the content.
Just to this check before actually displaying any content.

Not if the user is directly accessing a non-php file, i.e. a pdf.

hell, if read file gets me bush, i'm all over it!
thanks for the tip
After hard work and many attempts I found this:
/* logging test coming at this line */
header("Content-Type: application/pdf");
$fname='not1.pdf';
readfile($fname);
?>
This is quite enough for me, the address keeps being ........./*.php so for
unlogged user the site will not be accessible.
Many thanks...

For authentication it still uses HTTP authentication.
