Is SHA sufficient for checking file duplication? (sha1_file in PHP)

Suppose you wanted to make a file hosting site for people to upload their files and send a link to their friends to retrieve it later and you want to insure files are duplicated where we store them, is PHP's sha1_file good enough for the task? Is there any reason to not use md5_file instead?
For the frontend, it'll be obscured using the original…
