How Can I Create And Write Files In Magento 2 Extension Programmatically

I am writing a Magento 2 extension, I would like to know how to create and write files within Magento 2 extension

You can use Magento 2 core class Magento\Framework\Filesystem to handle file operations.

$directory = "/";
$FileName = "test.txt";
$contents = "test content for create and write files programmatically in Magento 2";

$object = \Magento\Framework\App\ObjectManager::getInstance();
$filesystem = $object->get('Magento\Framework\Filesystem');
$writer = $filesystem->getDirectoryWrite($directory);
$file = $writer->openFile($FileName, 'w');
try {
    $file->lock();
    try {
        $file->write($contents);
    }
    finally {
        $file->unlock();
    }
}
finally {
    $file->close();
}
