I was just wondering what "register_globals" actually is about? I have a Joomla installation I just did and it is just imforming me that it is turned off. What is it and what does it do?
Register_globals is a PHP configuration variable. If it is OFF, the Form POST and GET variables can only be accessed as the $_POST or $_GET associative array. e.g. the name field in form will be seen in the action script as $_POST['name'] If it is ON, the name field in form can be accessed both as $_POST['name'] or $name. For security reasons, the default setting nowadays is that it is kept OFF.
Generally you can turn this off in the .htaccess file in your public_html But if your hosting is running phpsuexec you may need to have this done in a php.ini file Really just depends what host you have. Some hosts may not have the option to change this. You may need to ask them to do this for you. Keep in mind when this is done a symlink must be added for all files for this to apply to. Its better to just ask your hosting provider to help on this.
