How can developers effectively debug and test PHP redirects without compromising the functionality of the redirection process?

When debugging and testing PHP redirects, developers can use browser developer tools to inspect network requests and responses, check for any errors in the redirect logic, and ensure that the redirection process is functioning correctly. Additionally, developers can use tools like Xdebug to step through the code and identify any issues in the redirect logic without affecting the functionality of the redirection process.

// Example code snippet for debugging and testing PHP redirects

// Check if the redirect logic is working correctly
if ($condition) {
    header("Location: https://example.com/new-page.php");
    exit();
} else {
    // Handle the redirect condition
}
