How can Joomla user data be automatically transferred to another database table in PHP?

To automatically transfer Joomla user data to another database table in PHP, you can use a script that retrieves the user data from the Joomla database and inserts it into the new database table. This can be achieved by connecting to both databases, querying the Joomla database for user data, and then inserting that data into the new table.

// Connect to Joomla database
$joomla_db = new PDO("mysql:host=localhost;dbname=joomla_db", "username", "password");

// Connect to new database
$new_db = new PDO("mysql:host=localhost;dbname=new_db", "username", "password");

// Retrieve Joomla user data
$query = $joomla_db->query("SELECT * FROM #__users");
$users = $query->fetchAll(PDO::FETCH_ASSOC);

// Insert user data into new database table
foreach($users as $user) {
    $stmt = $new_db->prepare("INSERT INTO new_table (username, email) VALUES (:username, :email)");
    $stmt->execute(array(':username' => $user['username'], ':email' => $user['email']));
}
