How can PHP scripts be used to allow comments on MySQL tables?

To allow comments on MySQL tables using PHP scripts, you can create a separate table to store the comments related to each record in the main table. This new table can have fields such as comment_id, record_id (to link to the main table), commenter_name, comment_text, and timestamp. You can then use PHP scripts to retrieve and display the comments associated with each record. 

// Connect to MySQL database
$connection = mysqli_connect("localhost", "username", "password", "database");

// Retrieve comments for a specific record
$record_id = 1;
$query = "SELECT * FROM comments WHERE record_id = $record_id";
$result = mysqli_query($connection, $query);

// Display comments
while($row = mysqli_fetch_assoc($result)) {
    echo "<p><strong>{$row['commenter_name']}</strong>: {$row['comment_text']}</p>";
}

// Add a new comment to a record
$commenter_name = "John";
$comment_text = "This is a great record!";
$query = "INSERT INTO comments (record_id, commenter_name, comment_text) VALUES ($record_id, '$commenter_name', '$comment_text')";
mysqli_query($connection, $query);

// Close MySQL connection
mysqli_close($connection);
