How can PHP beginners effectively troubleshoot issues with passing variables through links?

When passing variables through links in PHP, beginners may encounter issues with the variable not being correctly received on the destination page. To troubleshoot this, ensure that the variable is properly encoded in the link using `urlencode()` and decoded on the destination page using `urldecode()`. Additionally, check that the variable is being passed in the correct format (e.g., `$_GET['variable']`) and that the link is structured correctly. 

// Sending page
$variable = "example";
$encoded_variable = urlencode($variable);
echo "<a href='destination.php?var=$encoded_variable'>Link</a>";

// Destination page
$received_variable = urldecode($_GET['var']);
echo $received_variable;
