I tried to create directory and file and then put content in file programmatically but it does not work. Here is my code in sample.phtml 

<?php $om = \Magento\Framework\App\ObjectManager::getInstance(); /** @var \Magento\Framework\Filesystem $filesystem */ $filesystem = $om->get('Magento\Framework\Filesystem'); $directoryList = $om->get('Magento\Framework\App\Filesystem\DirectoryList'); /** @var \Magento\Framework\Filesystem\Directory\WriteInterface|\Magento\Framework\Filesystem\Directory\Write $writer */ $media_url = getMediaBaseUrl(); $writer = $filesystem->getDirectoryWrite($media_url."module1/"); /** @var \Magento\Framework\Filesystem\File\WriteInterface|\Magento\Framework\Filesystem\File\Write $file */ $contents = "ddddddddddddddddddddddddddd"; $relativeFileName = "sample.txt"; $file = $writer->openFile($relativeFileName, 'w'); try { $file->lock(); try { $file->write($contents); } finally { $file->unlock(); } } finally { $file->close(); } function getMediaBaseUrl() { /** @var \Magento\Framework\ObjectManagerInterface $om */ $om = \Magento\Framework\App\ObjectManager::getInstance(); /** @var \Magento\Store\Model\StoreManagerInterface $storeManager */ $storeManager = $om->get('Magento\Store\Model\StoreManagerInterface'); /** @var \Magento\Store\Api\Data\StoreInterface|\Magento\Store\Model\Store $currentStore */ $currentStore = $storeManager->getStore(); return $currentStore->getBaseUrl(\Magento\Framework\UrlInterface::URL_TYPE_MEDIA); } ?>

Finally, I got a solution for creating files and contents programmatically in Magento 2.

Here is a code

<?php try { $om = \Magento\Framework\App\ObjectManager::getInstance(); $filesystem = $om->get('Magento\Framework\Filesystem'); $directoryList = $om->get('Magento\Framework\App\Filesystem\DirectoryList'); $media = $filesystem->getDirectoryWrite($directoryList::MEDIA); $contents = "ddddddddddddddddddddddddddd"; $media->writeFile("module1/sample.txt",$contents); } catch(Exception $e) { echo $e->getMessage(); } ?>

  • Hello, If i have module xml file then what should i pass into getDirectoryWrite function? Commented Sep 14, 2018 at 12:13
  • you should pass same directory of magento. if your custom module then you have to create folder in media folder. you have to change name "module1" by your module name Commented Sep 22, 2018 at 23:34

    Good solution, but you should inject the dependency (only \Magento\Framework\Filesystem needed) into the constructor instead of using the object manager. Instead of $directoryList::MEDIA you can use \Magento\Framework\App\Filesystem\DirectoryList::MEDIA. Commented Apr 27, 2021 at 10:53

Url and directory are two different things

You are using

$currentStore->getBaseUrl(\Magento\Framework\UrlInterface::URL_TYPE_MEDIA)

You have to use

$mediaPath=$filesystem->getDirectoryRead(\Magento\Framework\App\Filesystem\DirectoryList::MEDIA)->getAbsolutePath(); $writer = $filesystem->getDirectoryWrite(mediaPath."module1".DS);

instead of 

$writer = $filesystem->getDirectoryWrite($media_url."module1/");
