What are the best practices for ensuring data integrity when using UPDATE queries in PHP without transactions in MySQL?

When using UPDATE queries in PHP without transactions in MySQL, it is important to ensure data integrity by validating input data, sanitizing user input to prevent SQL injection attacks, and using error handling to catch any potential issues during the update process. Additionally, you can implement a check to verify that the update query was successful before proceeding with any further actions. 

// Validate input data
$id = $_POST['id'];
$name = $_POST['name'];

// Sanitize user input
$id = filter_var($id, FILTER_SANITIZE_NUMBER_INT);
$name = filter_var($name, FILTER_SANITIZE_STRING);

// Update query
$update_query = "UPDATE table SET name = '$name' WHERE id = $id";

// Execute the query
$result = mysqli_query($connection, $update_query);

// Check if the update was successful
if($result) {
    echo "Update successful!";
} else {
    echo "Update failed. Please try again.";
}
