What are some best practices for implementing a time window of every 12 hours for voting in a PHP script?

To implement a time window of every 12 hours for voting in a PHP script, you can use a combination of storing the last vote timestamp in a database and checking if the current time is within the 12-hour window before allowing a new vote. 

// Assuming $lastVoteTimestamp is the timestamp of the last vote stored in the database
$currentTime = time();
$twelveHoursAgo = $currentTime - (12 * 60 * 60);

if ($lastVoteTimestamp < $twelveHoursAgo) {
    // Allow the user to vote
    // Update the last vote timestamp in the database to $currentTime
} else {
    // Display an error message or prevent the user from voting
}
