Uploading files in Symfony is conceptually no different from other PHP platforms, but still has its own features due to the presence of additional tools provided by the framework.

First of all, it is worth noting that there are ready-made solutions that solve the task at hand. I strongly recommend familiarizing yourself with them, and only after that, if you decide that they do not suit you, implement your own solution.

In this note we will try to show possible ways to solve the task, using both ready-made solutions (VichUploaderBundle, IphpFileStoreBundle), and using our own implementation (in Symfony controllers and admin classes from the SonataAdminBundle).
