However, I will show how magento does it or you can say the recommended way in Magento 2.

So for example I will create a csv file with customers list with columns as CustomerId, Customer Name and Customer Email.

How to Create a CSV file in Magento 2

\Magento\Framework\App\Response\Http\FileFactory used to create CSV and download CSV by Magento way. create() function in FileFactory.php is used for create CSV file.

There are many other ways to download CSV files using Core PHP script but its not the best way to use within the Magento Coding standard.


namespace Dolphin\Csv\Controller\Index;

use Magento\Framework\App\Action\Action;
use Magento\Framework\App\Action\Context;
use Magento\Framework\App\Filesystem\DirectoryList;

class CreateCsv extends Action
    public function __construct(
        Context $context,
        \Magento\Framework\Filesystem $filesystem,
        \Magento\Customer\Model\CustomerFactory $customerFactory
        $this->customerFactory = $customerFactory;
        $this->directory = $filesystem->getDirectoryWrite(DirectoryList::VAR_DIR);

    public function execute()
        $filepath = 'export/allcustomer.csv';
        $stream = $this->directory->openFile($filepath, 'w+');

        $header = ['CustomerId', 'Customer Name', 'Customer Email'];

        $collection = $this->customerFactory->create()->getCollection();
        foreach ($collection as $customer) {
            $customerData = [];
            $customerData[] = $customer->getId();
            $customerData[] = $customer->getName();
            $customerData[] = $customer->getEmail();

This will create allcustomer.csv file under var/export folder.
