What is the significance of the "register_globals" setting in PHP configuration?

The "register_globals" setting in PHP configuration allows variables to be automatically created from user input, which can lead to security vulnerabilities such as injection attacks and variable collisions. To solve this issue, it is recommended to disable the "register_globals" setting in the php.ini file or in the .htaccess file.

// Disable register_globals in php.ini
// Add the following line to php.ini
// register_globals = Off

// Disable register_globals in .htaccess
// Add the following line to .htaccess
// php_flag register_globals off
