How can user tracking data be effectively stored and managed in a PHP application?

User tracking data can be effectively stored and managed in a PHP application by utilizing a database to store the data. By creating a table specifically for tracking data and inserting new records for each user interaction, the data can be easily managed and analyzed. Additionally, using SQL queries to retrieve and update the tracking data allows for efficient data manipulation. 

// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "tracking_data";
$conn = new mysqli($servername, $username, $password, $dbname);

// Create a table for tracking data
$sql = "CREATE TABLE tracking (
    id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
    user_id INT(6) UNSIGNED,
    page_visited VARCHAR(255),
    timestamp TIMESTAMP
)";
$conn->query($sql);

// Insert new tracking data
$user_id = 123;
$page_visited = "/home";
$timestamp = date("Y-m-d H:i:s");
$sql = "INSERT INTO tracking (user_id, page_visited, timestamp) VALUES ('$user_id', '$page_visited', '$timestamp')";
$conn->query($sql);

// Retrieve tracking data
$sql = "SELECT * FROM tracking WHERE user_id = '$user_id'";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        echo "User ID: " . $row["user_id"]. " - Page Visited: " . $row["page_visited"]. " - Timestamp: " . $row["timestamp"]. "<br>";
    }
} else {
    echo "0 results";
}

// Close the database connection
$conn->close();
