How can the sqlite_next function in PHP be used effectively when fetching data from a SQLite database?

The sqlite_next function in PHP can be used effectively when fetching data from a SQLite database by iterating over the result set one row at a time. This function allows you to move the internal result pointer to the next row in the result set, making it easy to process each row sequentially. By using sqlite_next in a loop, you can efficiently retrieve and process data from the database without loading the entire result set into memory at once. 

// Open a connection to the SQLite database
$db = new SQLite3('database.db');

// Execute a query to fetch data from the database
$query = $db->query('SELECT * FROM table');

// Loop through the result set and fetch each row
while ($row = $query->fetchArray()) {
    // Process the data from the current row
    echo $row['column1'] . ' ' . $row['column2'] . "\n";
    
    // Move the internal result pointer to the next row
    sqlite_next($query);
}

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