How can comment tags be effectively used to highlight specific lines of code in a PHP forum discussion?

To highlight specific lines of code in a PHP forum discussion, you can use comment tags to make them stand out. By wrapping the code in comment tags, you can easily distinguish it from the rest of the text and draw attention to the important parts. This can be especially useful when discussing complex or problematic code snippets.

// Highlighted code snippet
// This is the important line of code that needs attention
$variable = 'value';
