What are the potential pitfalls of using relative links within PHP functions?

When using relative links within PHP functions, the potential pitfalls include the links not resolving correctly based on the current working directory of the script, leading to broken links or incorrect paths. To solve this issue, it is recommended to use absolute paths or to dynamically generate the correct path based on the server environment. 

// Example of using absolute path within PHP function to avoid pitfalls of relative links
function generateLink($page) {
    $basePath = "http://www.example.com/";
    return $basePath . $page;
}

$link = generateLink("about.php");
echo $link;
