Discussion on user authentication of PHP (i.)
Popcorn September 25, 2001 Www.westxj.net
When browsing the Web site, we often encounter some Web pages will require the user and password verification,
This requires us to write the appropriate authentication program to implement this feature. Here are some of my learning process and experience, I hope to help you.
(i) Single-user authentication based on HTTP authentication:
We use the function header () to send HTTP headers to force validation, the client browser pop-up to enter the user name and Password dialog box, when the client's user input information, is transferred to the server after the $php_auth_user, $PHP _auth_ PW the two global variables. Using these variables, you can authenticate users and passwords.
The following program can perform simple authentication
?
if ($PHP _auth_user!= ' Jane ' | | $PHP _auth_pw!= ' 123456 ')
{
Header ("Www-authenticate:basic realm=\" "Popcorn landing \");
Header ("http/1.0 401 Unauthorized");
echo "Authentication Error! ";
Exit
}
?>
(Note: When using HTTP authentication, you must run it as an Apache module, and if you are using a CGI-mode PHP, you will not be able to implement HTTP based authentication.) ）
