SQLite3
SQLite is a C-language library that implements a small, fast, self-contained, high-reliability, full-featured, SQL database engine.
The related extension is SQLite3. It allows the creation and usage of file-based or memory-based databases.
SQLite3 is also available with PDO, with the pdo_sqlite engine.
<?php
$db = new SQLite3('my.sqlite3');
$results = $db->query('SELECT bar FROM foo');
while ($row = $results->fetchArray()) {
var_dump($row);
}
?>
