How can one ensure that SQLite is properly configured and functioning in a PHP environment?

To ensure that SQLite is properly configured and functioning in a PHP environment, you can check if the SQLite extension is enabled in your PHP configuration file (php.ini). You can also test the connection to the SQLite database by running a simple query to verify that it works correctly.

// Check if SQLite extension is enabled
if (!extension_loaded('sqlite3')) {
    die('SQLite extension is not enabled');
}

// Test SQLite connection
try {
    $db = new SQLite3('path/to/database.db');
    $result = $db->query('SELECT * FROM table_name');
    while ($row = $result->fetchArray()) {
        // Process data
    }
    $db->close();
} catch (Exception $e) {
    echo 'SQLite connection failed: ' . $e->getMessage();
}
