How does the use of special characters like "&" affect link generation in PHP?

Special characters like "&" can cause issues in link generation in PHP because they are reserved characters in URLs and can be misinterpreted by the browser. To solve this issue, you can use the urlencode() function in PHP to encode special characters before including them in the URL. 

<?php
$param1 = "value1";
$param2 = "value&2";

$url = "http://example.com/script.php?param1=" . urlencode($param1) . "&param2=" . urlencode($param2);

echo $url;
?>
