What are some alternatives to using MySQL for storing user data in PHP applications?

One alternative to using MySQL for storing user data in PHP applications is to use SQLite. SQLite is a lightweight, serverless database engine that is easy to set up and use for small to medium-sized applications. Another option is to use PostgreSQL, which is a powerful open-source relational database system that offers advanced features and scalability. Additionally, you can consider using MongoDB, a NoSQL database that is designed for storing and querying JSON-like documents. 

// Example of using SQLite to store user data in a PHP application
$db = new SQLite3('users.db');

// Create a table to store user data
$db->exec('CREATE TABLE users (id INTEGER PRIMARY KEY, username TEXT, email TEXT)');

// Insert user data into the table
$db->exec("INSERT INTO users (username, email) VALUES ('john_doe', 'john.doe@example.com')");

// Retrieve user data from the table
$results = $db->query('SELECT * FROM users');
while ($row = $results->fetchArray()) {
    echo $row['username'] . ' - ' . $row['email'] . '<br>';
}

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