How can PHP developers ensure that updating multiple records in a single form submission is efficient and error-free?

When updating multiple records in a single form submission, PHP developers can ensure efficiency and avoid errors by using prepared statements to prevent SQL injection attacks, validating user input to ensure data integrity, and using transactions to maintain data consistency. 

<?php
// Assuming $db is a PDO object connected to the database

// Begin a transaction
$db->beginTransaction();

// Loop through the submitted data to update multiple records
foreach ($_POST['records'] as $record) {
    $stmt = $db->prepare("UPDATE table SET column = :value WHERE id = :id");
    $stmt->bindParam(':value', $record['value']);
    $stmt->bindParam(':id', $record['id']);
    $stmt->execute();
}

// Commit the transaction
$db->commit();
?>
