I did not try it because i did not have the time.  I just  tried it and did not get 
those same results.

After the first login it did create the file, I deleted, refreshed, no file...did what 
it is supposed to.

I am however using a CVS version of 4.0.5, have you tried it with the CVS version?

Are you running Apache as standalone or inetd?

If I remember right, PHP/Apache/inetd likes to lose env variables.

// Header("WWW-Authenticate: Basic realm="Realm"");

if (!$PHP_AUTH_USER) {
        Header("WWW-Authenticate: Basic realm="Realm"");
        Header("HTTP/1.0 401 Unauthorized");
} else
        echo "else";


Compiler: gcc 2.95.2
Make: GNU 3.79
FSU Pthreads: 3.8

Apache: 1.3.19
MySQL: 3.23.36
PHP: 4.0.4pl1

PHP is compiled as an Apache module with the following options:

--with-mysql --with-apache --with-pdflib --with-gd --with-trans-sid 
--enable-track-vars --enable-sysvsem --enable-sysvshm

Description of problem:

Both sides of the IF construct are being executed when testing the $PHP_AUTH_USER 
variable AND issuing the header function. I posted this question in the general mail 
list but have received any reponse from

Using the script list above, follow the steps shown below to produce this problem:

1. Close all instances of your browser (I am using IE-5.01 and I have not tried any 
other browsers). However I don't believe it is a browser issue.

2. Run the script shown above.

3. Enter some user ID and password... Everything so far works fine.

4. Look in the directory where the script is stored. There should be a file called 
xxxx. This indicates that $PHP_AUTH_USER was NOT set.

5. Remove the file xxxx.

6. Refresh the browser. Look for the file xxxx. Notice that xxxx is present; which 
should only happen if $PHP_AUTH_USER is NOT set....YET "else" was printed on screen 
which indicates that $PHP_AUTH_USER IS set.

7. Uncomment the commented "header" line and notice that a user ID and password prompt 
is always issued in this case.

My questions are:

1. Why are both sides of the conditional "If (!isset($PHP_AUTH_USER))" being executed?

2. Why, when $PHP_AUTH_USER is not set, the 'exec(">xxxx")' runs on subsequent 
refreshes, but no prompt for a new user ID and password is issued?

3. Why, if a authenticate header is sent before testing, a user ID and password prompt 
is issued?

Thanks for taking a look at this.
