How can PHP developers ensure data integrity when moving records to a "trash" or "papierkorb" table?

When moving records to a "trash" or "papierkorb" table, PHP developers can ensure data integrity by first validating the data being moved, ensuring that it meets the required criteria for being moved to the trash table. They should also consider implementing a transaction to ensure that the move operation is atomic and can be rolled back in case of any issues. Lastly, they should update any foreign key constraints or related records to reflect the move. 

// Validate the data being moved to trash table
// Implement a transaction for atomicity
// Update any related records or foreign key constraints

try {
    $pdo->beginTransaction();
    
    // Validate data
    // Move record to trash table
    
    // Update related records or foreign key constraints
    
    $pdo->commit();
} catch (PDOException $e) {
    $pdo->rollBack();
    echo "Error moving record to trash table: " . $e->getMessage();
}
