What best practices should be followed when updating or deleting database records in PHP scripts?

When updating or deleting database records in PHP scripts, it is important to use prepared statements to prevent SQL injection attacks. Additionally, always validate user input before executing any database queries to ensure data integrity and security. 

// Update database record using prepared statements
$stmt = $pdo->prepare("UPDATE table_name SET column1 = :value1 WHERE id = :id");
$stmt->bindParam(':value1', $value1);
$stmt->bindParam(':id', $id);
$stmt->execute();

// Delete database record using prepared statements
$stmt = $pdo->prepare("DELETE FROM table_name WHERE id = :id");
$stmt->bindParam(':id', $id);
$stmt->execute();
