If a install ios7 for my iphone do i lost everything i have?

Do i lose everthing like photos, apps, music?

I installed it and no apps, photos, or music were lost so you should be good to go! It's always a good idea to back up first though…

No, you don't even have to connect your device to a computer. (Unless you don't have Wi-Fi or something) just go to settings > general > software updates.
