How can a PHP developer ensure that each comment contains the ID of the author for easy retrieval?

To ensure that each comment contains the ID of the author for easy retrieval, a PHP developer can modify the comment structure to include the author's ID as a field. This can be achieved by updating the database schema to include a foreign key reference to the author's ID in the comments table. When inserting a new comment, the developer should ensure that the author's ID is included in the comment data before saving it to the database. 

// Assuming $authorId contains the ID of the current author
$authorId = 1; // Example author ID

// Inserting a new comment with the author's ID
$comment = "This is a new comment.";
$authorId = $authorId; // Assuming $authorId contains the ID of the author
$commentId = 123; // Example comment ID

// Save the comment to the database with the author's ID
$query = "INSERT INTO comments (comment, author_id) VALUES ('$comment', $authorId)";
// Execute the query using your preferred method (e.g., mysqli_query, PDO, etc.)
