What are some potential pitfalls or drawbacks of inserting multiple rows at once in a database using PHP?

One potential pitfall of inserting multiple rows at once in a database using PHP is the risk of encountering errors or data inconsistencies if any of the rows fail to insert properly. To mitigate this risk, you can use transactions in PHP to ensure that all rows are either inserted successfully or none are inserted at all. 

// Establish a database connection
$pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');

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

try {
    // Prepare the SQL statement for inserting multiple rows
    $stmt = $pdo->prepare("INSERT INTO my_table (column1, column2) VALUES (?, ?)");

    // Loop through an array of data to be inserted
    foreach ($data as $row) {
        $stmt->execute([$row['value1'], $row['value2']]);
    }

    // Commit the transaction if all inserts are successful
    $pdo->commit();
} catch (Exception $e) {
    // Rollback the transaction if an error occurs
    $pdo->rollBack();
    echo "Error: " . $e->getMessage();
}
