    This is the example of HTTP authentication from php.net. I've read it 10 times and tried it, but I can't get it to work. Can someone explain what happens here? is $PHP_AUTH_USER an environment variable? Can I access it from every page?

    if(!isset($PHP_AUTH_USER)) {
    Header("WWW-Authenticate: Basic realm="My Realm"");
    Header("HTTP/1.0 401 Unauthorized");
    echo "Text to send if user hits Cancel buttonn";
    } else {
    echo "Hello $PHP_AUTH_USER.<P>";
    echo "You entered $PHP_AUTH_PW as your password.<P>";

    I've heard that there is a way to make variabes availible to all pages, putting them in some sort of global file. Can I use that for authentication?

    This type of authentication only works if PHP is installed as an Apache module. It won't work if you are using PHP as a CGI.
