What potential pitfalls should be considered when transferring data between tables in PHP?

One potential pitfall when transferring data between tables in PHP is the risk of data loss or corruption if the transfer process is not handled carefully. To avoid this, it is important to properly validate the data being transferred and ensure that the destination table has the necessary columns to accommodate the data. Additionally, it is crucial to use transactions to ensure that the data is transferred atomically, so that either all of the data is transferred successfully or none of it is. 

// Example code snippet for transferring data between tables in PHP using transactions

try {
    $pdo->beginTransaction();

    // Validate data and perform necessary checks before transferring
    // Transfer data from source table to destination table

    $pdo->commit();
    echo "Data transfer successful";
} catch (Exception $e) {
    $pdo->rollBack();
    echo "Error transferring data: " . $e->getMessage();
}
