Why is it important to avoid using register_globals in PHP scripts, as mentioned in the forum discussion?

Using register_globals in PHP scripts can lead to security vulnerabilities, as it allows external input to automatically create global variables in the script. This can be exploited by malicious users to manipulate variables and potentially execute harmful actions on the server. To avoid this, it is recommended to disable register_globals in the PHP configuration and instead use superglobal arrays like $_GET, $_POST, and $_SESSION to access user input. 

// Disable register_globals in php.ini configuration file
// Set register_globals = Off

// Access user input using superglobal arrays
$myVariable = $_POST['myInput'];
