How can PHP developers avoid security vulnerabilities like register_globals?

Register_globals can be avoided by not relying on them for variable initialization. Instead, developers should use superglobal arrays such as $_GET, $_POST, and $_REQUEST to access user input securely. 

// Avoid using register_globals by accessing variables through superglobal arrays
$username = isset($_POST['username']) ? $_POST['username'] : '';
$password = isset($_POST['password']) ? $_POST['password'] : '';
