How can a PHP function be redirected to a login page if the user is not identified, without causing issues with the redirection?

When a user is not identified in a PHP function, you can redirect them to a login page to authenticate themselves. To avoid issues with the redirection, you can use conditional statements to check if the user is logged in or not before redirecting them. This ensures that only unauthorized users are redirected to the login page. 

<?php
// Check if user is not identified
if(!isset($_SESSION['user_id'])) {
    header("Location: login.php");
    exit;
}

// Your PHP function code here
