How can PHP developers avoid errors when passing and displaying variables in generated links?

To avoid errors when passing and displaying variables in generated links in PHP, developers should ensure that the variables are properly sanitized to prevent injection attacks and unexpected behavior. One way to achieve this is by using the `urlencode()` function to encode the variables before appending them to the link. 

// Example of generating a link with sanitized variables
$variable1 = "example value";
$variable2 = "another value";

$link = "https://example.com/page.php?var1=" . urlencode($variable1) . "&var2=" . urlencode($variable2);

echo '<a href="' . $link . '">Link</a>';
