How can PHP developers ensure that data is inserted into a database in the correct order when using loops to process CSV files?

When processing CSV files using loops in PHP, developers can ensure that data is inserted into a database in the correct order by using transactions. By starting a transaction before the loop begins and committing it after all the data has been processed, the integrity of the data insertion can be maintained even if an error occurs during the process. 

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

// Loop through the CSV file
foreach ($csvData as $row) {
    // Process and insert data into the database
    // Example: $pdo->query("INSERT INTO table_name (column1, column2) VALUES ('$row[0]', '$row[1]')");
}

// Commit the transaction
$pdo->commit();
