How can a PHP script implement a feature to block a user's name for 24 hours?

To implement a feature to block a user's name for 24 hours in PHP, you can store the blocked user's name and the timestamp of when the block was initiated in a database or a file. When a user tries to use the blocked name, you can check the timestamp to see if 24 hours have passed since the block was initiated. If the time limit has not elapsed, you can prevent the user from using the name. 

// Assuming $blockedUsers is an array containing blocked usernames and timestamps

function isUserBlocked($username) {
    global $blockedUsers;
    
    if (array_key_exists($username, $blockedUsers)) {
        if (time() - $blockedUsers[$username] < 86400) { // 24 hours in seconds
            return true;
        } else {
            unset($blockedUsers[$username]); // Unblock user after 24 hours
        }
    }
    
    return false;
}

// Example usage
$blockedUsers = []; // Initialize array
$username = "blocked_user";

$blockedUsers[$username] = time(); // Block user
if (isUserBlocked($username)) {
    echo "User is blocked for 24 hours.";
} else {
    echo "User is not blocked.";
}
