In what scenarios should forum tags be used to improve code readability in PHP discussions?
Forum tags should be used in PHP discussions when there are multiple topics or categories being discussed within a forum thread. By using tags, users can easily navigate and filter through discussions related to specific topics, improving the overall readability and organization of the forum.
// Example of using forum tags in PHP discussions
$tags = array("PHP", "Code Readability", "Forum");
foreach($tags as $tag) {
echo "<a href='#'>$tag</a> ";
}
