How can one troubleshoot issues with passing variables in a PHP link?

When passing variables in a PHP link, ensure that the variables are properly encoded using `urlencode()` to handle special characters and spaces. If the variables are not being passed correctly, check the syntax of the link and make sure that the variables are correctly appended using the `?` and `&` symbols. Additionally, check for any errors in the PHP code that generates the link. 

// Encode the variables before passing them in the link
$variable1 = urlencode($variable1);
$variable2 = urlencode($variable2);

// Construct the link with the variables
$link = "page.php?var1=$variable1&var2=$variable2";

// Output the link
echo "<a href='$link'>Click here</a>";
