Simple and relativity safe login scripts for web sites with secret contains and
multiple users. All traffic is loged to MySQL database for possible latter analysis...
This scrips work correctly only with PHP 4.2 and higher and default php.ini settings
( register_globals option is turned off, so some older scripts need revitalisation )
hidden inputs ( client detection variables must be register with new EGPCS futures )
in form go to MySQL log file. Set of new EGPCS values contain:
$_ENV -- system environment variables
$_SERVER -- server variables ( HTTP_USER_AGENT etc )
$_SESSION -- session variables
$_GET -- variables in the query string ( from GET forms, too )
$_POST -- variables submitted from POST forms
$_COOKIE -- cookie variables
$_REQUEST -- everything in $_GET, $_POST, and $_COOKIE
Scripts are tested with Win2000/IIS 5/PHP 4.2.1 and working with older versions of
PHP ( and Apache server), too, but intrusion is possible via browser command line input
( in this case: http://localhost/log2db.php?authorized=1 )
