What is the best way to store a user's ID from a Facebook App on a server using PHP?

To store a user's ID from a Facebook App on a server using PHP, you can use a database to store the user's ID along with any other relevant information. You can create a table in the database to store the user's ID and any additional data you may need. When a user logs in to your Facebook App, you can retrieve their ID from the Facebook API and store it in the database for future reference. 

// Assuming you have already retrieved the user's ID from the Facebook API
$user_id = '123456789';

// Connect to your database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "your_database";

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

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

// Insert the user's ID into the database
$sql = "INSERT INTO users (user_id) VALUES ('$user_id')";

if ($conn->query($sql) === TRUE) {
    echo "User ID stored successfully";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}

$conn->close();
