What are the potential benefits of using a SQLite database in a PHP crawler?

When building a PHP crawler, it is essential to efficiently store and manage the crawled data. Using a SQLite database can provide benefits such as lightweight file-based storage, fast read and write operations, and easy integration with PHP due to its native support. By utilizing a SQLite database in a PHP crawler, you can effectively store and retrieve crawled data, making the crawling process more organized and efficient. 

// Connect to SQLite database
$db = new SQLite3('crawler_data.db');

// Create table to store crawled data
$db->exec('CREATE TABLE IF NOT EXISTS crawled_data (id INTEGER PRIMARY KEY, url TEXT, content TEXT)');

// Insert crawled data into the database
$url = "https://example.com";
$content = "Crawled content goes here";
$db->exec("INSERT INTO crawled_data (url, content) VALUES ('$url', '$content')");

// Retrieve crawled data from the database
$results = $db->query("SELECT * FROM crawled_data");
while ($row = $results->fetchArray()) {
    echo "URL: " . $row['url'] . " - Content: " . $row['content'] . "\n";
}

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