How can PHP be connected to SQLite databases effectively?

To connect PHP to SQLite databases effectively, you can use the PDO (PHP Data Objects) extension which provides a flexible and secure way to access databases. You need to create a PDO object with the SQLite database file path as a parameter, then you can perform various database operations using this object.

// SQLite database file path
$db_file = 'path/to/database.db';

// Create a PDO object to connect to the SQLite database
$pdo = new PDO("sqlite:$db_file");

// Example query to select data from a table
$stmt = $pdo->query("SELECT * FROM table_name");

// Fetch data from the query result
while ($row = $stmt->fetch()) {
    // Process the data here
}

// Close the database connection
$pdo = null;
