What is the intended behavior for the link returned by the PHP function in the code?

The issue with the current code is that the link returned by the PHP function is missing the protocol (http:// or https://). To solve this issue, we need to check if the link provided already contains a protocol. If it does not, we need to prepend the link with a default protocol such as "http://". 

function fixLink($link) {
    if (strpos($link, 'http://') === false && strpos($link, 'https://') === false) {
        $link = 'http://' . $link;
    }
    return $link;
}

// Example usage
$link = 'example.com';
$fixedLink = fixLink($link);
echo $fixedLink;
