In the context of PHP development, how can developers efficiently manage and display user names from different tables in a messaging system?

To efficiently manage and display user names from different tables in a messaging system, developers can use SQL JOIN queries to retrieve the necessary information. By joining the tables containing user names with the messages table, developers can easily fetch and display the user names associated with each message. 

// Assuming we have tables named users and messages with user_id as the foreign key

$query = "SELECT messages.message, users.username 
          FROM messages 
          JOIN users ON messages.user_id = users.id";

$result = mysqli_query($connection, $query);

if(mysqli_num_rows($result) > 0) {
    while($row = mysqli_fetch_assoc($result)) {
        echo $row['username'] . ": " . $row['message'] . "<br>";
    }
} else {
    echo "No messages found.";
}
