If your application needs to store files (such as user-uploaded photos), it is often a good idea to use an object storage solution. This approach makes it easier to share files between multiple services and keeps your uploaded files separate from your code. You might want to explore MinIO for a fast, reliable, and S3-compatible solution.

If you would rather use local file storage, you can take advantage of the persistent storage included with your PHP instance. This storage is available at /persistent/storage/.

For example, to save an uploaded file, you can use the move_uploaded_file function like this:

move_uploaded_file($_FILES['image']['tmp_name'], '/persistent/storage/image.jpg');

For more information about file uploads in PHP, you can check the official documentation: https://www.php.net/manual/en/features.file-upload.php.

CAUTION: Always store data inside the /persistent/storage/ folder.

If your instance reboots or if you push code changes, any data stored outside the persistent storage may be lost.
