hashing in php

First of all, i don't know what is fingerprint. but i think the question was asking about hashing a string. and there are lots of ways in php that will help us hashing a string. but hash(string algo,string string[,bool raw_outputs]) is the most appropriate for this as this function can use different algorithms for hashing.this functin is new in php 5.

Question:
A fingerprint of a string can be determined using which of the following?

Answer:

1. md5()
2. hash()
3. fingerprint()
no such function.
4. None of the above
