In PHP polling scripts, how can the total number of votes be accurately calculated and displayed for users?

To accurately calculate and display the total number of votes in a PHP polling script, you can iterate through the database records containing the votes and sum up the vote counts. You can then display this total count to the users on the webpage. 

// Connect to your database
$pdo = new PDO('mysql:host=localhost;dbname=your_database', 'username', 'password');

// Query to select all the votes
$query = $pdo->query("SELECT SUM(vote_count) AS total_votes FROM votes");
$result = $query->fetch(PDO::FETCH_ASSOC);

// Display the total number of votes to the users
echo "Total votes: " . $result['total_votes'];
