What are some potential pitfalls when multiple scripts are accessing and manipulating data from a MySQL database simultaneously?

One potential pitfall when multiple scripts are accessing and manipulating data from a MySQL database simultaneously is the risk of data inconsistency or corruption. To prevent this, you can use transactions in your PHP scripts to ensure that all database operations are atomic and isolated from each other. This helps maintain data integrity by either committing all changes or rolling them back if an error occurs. 

// Start a transaction
$pdo->beginTransaction();

try {
    // Perform database operations here

    // Commit the transaction
    $pdo->commit();
} catch (Exception $e) {
    // Roll back the transaction if an error occurs
    $pdo->rollBack();
    echo "Transaction failed: " . $e->getMessage();
}
