How can JavaScript code affect the masking of PHP entries in a database?

JavaScript code cannot directly affect the masking of PHP entries in a database, as JavaScript runs on the client-side and PHP runs on the server-side. However, you can use JavaScript to send requests to a PHP script that handles database operations, such as masking entries before inserting them into the database. 

<?php
// Connect to database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Mask the entry before inserting into the database
$masked_entry = password_hash($_POST['entry'], PASSWORD_DEFAULT);

// Prepare and bind SQL statement
$stmt = $conn->prepare("INSERT INTO entries (entry) VALUES (?)");
$stmt->bind_param("s", $masked_entry);

// Execute the statement
$stmt->execute();

// Close the connection
$stmt->close();
$conn->close();
?>
