What potential issues can arise when integrating a MySQL database with a Joomla website using PHP?

One potential issue that can arise when integrating a MySQL database with a Joomla website using PHP is the risk of SQL injection attacks if user input is not properly sanitized. To prevent this, it is crucial to use prepared statements with parameterized queries to securely interact with the database. 

// Establish a connection to the MySQL database
$mysqli = new mysqli("localhost", "username", "password", "database");

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

// Prepare a parameterized query to prevent SQL injection
$stmt = $mysqli->prepare("SELECT * FROM users WHERE username = ?");
$stmt->bind_param("s", $username);

// Execute the query
$stmt->execute();

// Fetch the results
$result = $stmt->get_result();

// Process the results
while ($row = $result->fetch_assoc()) {
    // Do something with the data
}

// Close the statement and connection
$stmt->close();
$mysqli->close();
