Solution
Heroku File Systems
Heroku behavior varies depending a little on the stack you use. With Bamboo, most of the file system is read-only. With Cedar, it is ephemeral.
In either case, the file systems are not shared between dynos, and should not be used for storage. To reliably store data server-side, you will need to use the database (perhaps storing your uploads as blobs), or as external assets on another host or service.
Problem
I'm new to `HEROKU APPS`. In my heroku app i have a problem. that is I'm using a php script to save data on server. Example : ``` <?PHP $file = "example.txt"; $data = "Something..."; file_put_contents($file,$data); ?> ``` This PHP script run successfully and save data perfectly. But, when I deploy my APP to `HEROKU` to update -> in this precess `example.txt` file is automatically deleted.
