Examples

This code will display a permalink to a specific comment:

    echo '<a href="' . comment_link($comment) . '">Permalink to this comment</a>';
}

// Display the comment link with custom text
echo '<a href="' . comment_link($comment) . '">Go to this comment</a>';

This example demonstrates how to display a comment link with the author’s name:
