What are the potential advantages of using SQLite over a custom PHP textfile database for API functionality?

Using SQLite over a custom PHP textfile database for API functionality can offer several advantages. SQLite is a more robust and efficient database management system that provides better performance, scalability, and reliability compared to a custom textfile database. Additionally, SQLite supports SQL queries, transactions, and indexing, making it easier to work with complex data structures and retrieve information quickly.

// Using SQLite for API functionality
// Connect to SQLite database
$db = new SQLite3('api_database.db');

// Create a table for storing API data
$db->exec('CREATE TABLE IF NOT EXISTS api_data (id INTEGER PRIMARY KEY, data TEXT)');

// Insert data into the table
$db->exec("INSERT INTO api_data (data) VALUES ('example data')");

// Retrieve data from the table
$result = $db->query('SELECT * FROM api_data');

// Display the retrieved data
while ($row = $result->fetchArray()) {
    echo $row['data'] . "\n";
}

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