broken old iphone to new iphone

If you're lucky and you had the phone set to automatically back up to iCloud and to sync items to iCloud then restoring a new phone from a backup and signing into iCloud should restore most things. If the phone is switched on it and connected to power it may even have made a very recent backup and you should be able to recover pretty much everything. Here's a bunch of links related to that:Set up iCloud on your iPhone, iPad, or iPod touch - https://support.apple.com/HT208681

Then you'll have to get it repaired before you can't get anything not synced to your iCloud account from it.
