Can i sync my iphone to another computer without loosing my entire music library?

I have an entire library on my phone using music off my computer, however my computer is now broken and i'm using a laptop to now download my music, i'm facing a problem though because i don't want to loose all my music currently on my iphone.somebody please help me!

Don't do it! If you have the same itunes on you laptop with all the same songs and albums on it, then its fine. If not then you will loose all your songs. I synced my iphone onto my new computer and as it wasn't the same and didint have all the songs and albums i had on my other itunes, i lossed all my albums and songs:'
