I have a problem with PHP sessions.
I have developed a backend for a mobile app developed by another team of devs. The app send requests to my php scripts which collects data and send them to the mobile app.
The problem is that I have used PHP sessions and this way, if the mobile app doesn't send requests for 30 minutes, the session expires and the php scripts return bad or null values.
I have now to manage this issue and I'm wondering what is the best way to do it. Can I set the php.ini in order to make sessions never expire? Or do I have to tell developers to use Ajax to prevent session expiring? Or there is some better way?
