What are the best practices for updating database records in PHP to avoid unintentional data loss or corruption?

When updating database records in PHP, it is important to follow best practices to avoid unintentional data loss or corruption. One way to do this is by using prepared statements with parameterized queries to prevent SQL injection attacks. Additionally, always validate and sanitize user input before updating the database to ensure data integrity. Finally, consider implementing transactions to ensure that all database operations are completed successfully or rolled back in case of any errors. 

// Example of updating database records in PHP using prepared statements
$pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");

$id = $_POST['id'];
$newValue = $_POST['new_value'];

$stmt = $pdo->prepare("UPDATE mytable SET column_name = :new_value WHERE id = :id");
$stmt->bindParam(':new_value', $newValue);
$stmt->bindParam(':id', $id);
$stmt->execute();
