What are the potential risks of using text files for storing data in PHP?

Using text files for storing data in PHP can pose potential risks such as data corruption, security vulnerabilities, and limited scalability. To mitigate these risks, it is recommended to use a more secure and scalable database system like MySQL or SQLite for storing data. 

// Example of using SQLite for storing data instead of text files
// Connect to SQLite database
$db = new SQLite3('database.db');

// Create a table
$query = "CREATE TABLE IF NOT EXISTS users (id INTEGER PRIMARY KEY, name TEXT, email TEXT)";
$db->exec($query);

// Insert data into the table
$query = "INSERT INTO users (name, email) VALUES ('John Doe', 'john@example.com')";
$db->exec($query);

// Retrieve data from the table
$results = $db->query("SELECT * FROM users");
while ($row = $results->fetchArray()) {
    echo "Name: " . $row['name'] . ", Email: " . $row['email'] . "\n";
}

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