How can PHP beginners effectively troubleshoot and debug navigation-related issues on their websites?

To troubleshoot and debug navigation-related issues on websites, PHP beginners can start by checking for errors in their code, such as incorrect file paths or syntax errors. They can also use tools like browser developer tools to inspect network requests and console logs for any errors. Additionally, beginners can try echoing out variables or using var_dump to see the values being passed through their navigation code. Example PHP code snippet: 

<?php
// Check if the navigation links are working correctly
if($_SERVER['REQUEST_URI'] == '/index.php'){
    echo '<a href="/about.php">About</a>';
    echo '<a href="/contact.php">Contact</a>';
} elseif($_SERVER['REQUEST_URI'] == '/about.php'){
    echo '<a href="/index.php">Home</a>';
    echo '<a href="/contact.php">Contact</a>';
} elseif($_SERVER['REQUEST_URI'] == '/contact.php'){
    echo '<a href="/index.php">Home</a>';
    echo '<a href="/about.php">About</a>';
} else {
    echo '<a href="/index.php">Home</a>';
    echo '<a href="/about.php">About</a>';
    echo '<a href="/contact.php">Contact</a>';
}
?>
