What are common pitfalls when installing a PHP live chat script?

One common pitfall when installing a PHP live chat script is not properly configuring the database connection settings, leading to errors when trying to store or retrieve chat messages. To solve this, ensure that the database credentials in the script match those of your database server.

// Database connection settings
$servername = "localhost";
$username = "root";
$password = "password";
$dbname = "chat_db";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}
