How can a PHP developer effectively troubleshoot and identify a redirect loop causing an "Umleitungsfehler" error?

To effectively troubleshoot and identify a redirect loop causing an "Umleitungsfehler" error in PHP, the developer can start by checking the code for any unintended redirects or loops. They can also use browser developer tools to track the network requests and see if there is a continuous loop of redirects happening. Additionally, logging the redirect URLs in the code can help identify the source of the loop. 

// Check for redirect loop and prevent it
$redirectUrls = [];
$currentUrl = $_SERVER['REQUEST_URI'];

if (in_array($currentUrl, $redirectUrls)) {
    // Redirect loop detected, handle it accordingly
    die("Redirect loop detected");
} else {
    $redirectUrls[] = $currentUrl;
    // Perform the redirect as needed
    header("Location: new_page.php");
    exit();
}
