By combining. htaccess files and. htpasswd files are used to prevent users from accessing directories on some servers. These files contain information about the user being allowed access to a directory and their own password. HTTP authentication can be done by sending special HTTP header information instead of using the. htaccess file

<?php    if (!isset ($_server[' Php_auth_user ')) {        header ("Www-authenticate:basic realm=\" My Private area\ "" );        Header ("http/1.0 401 Unauthorized");        Print "You need valid credentials to get access!\n";        Exit;    } else {        if (($_server[' php_auth_user '] = = ' Mani ') && ($_server[' php_auth_pw '] = = ' w#m3nt0r ')) {            print " Welcome to the private area! ";        } else {            header ("Www-authenticate:basic realm=\" My Private area\ "");            Header ("http/1.0 401 Unauthorized");            Print "You need valid credentials to get access!\n";            Exit;        }    }? >x
