>Solution :

Ensure that your users table has a column named login_attempts. You can add this column using a SQL query like:
ALTER TABLE users ADD COLUMN login_attempts INT DEFAULT 0;
then.>
In your PHP login script, you need to check the login attempts before allowing a user to log in. If the number of login attempts exceeds a certain limit, you may want to lock the account or implement some delay to prevent brute force attacks.

Here’s a simplified example your php code, let we call "create_blocked.php":

<?php
$sql_update_attempts = "UPDATE users SET login_attempts = login_attempts + 1 WHERE username = ?";
    $stmt_update_attempts = $conn->prepare($sql_update_attempts);
    $stmt_update_attempts->bind_param("s", $username);
    $stmt_update_attempts->execute();
$max_attempts = 3;
    if ($stmt_update_attempts->affected_rows >= $max_attempts) {
        // Lock the account or implement other security measures
        echo "Account locked due to multiple failed login attempts.";
        exit();
    }
?>
