2 examples: Try:

date("W",mktime (0,0,0,12,31,2001))  gives week 53. 
This should be week 1 of year 2002.

date("W",mktime (0,0,0,1,2,2000))    gives week 0.
This should be week 52 of year 1999.

So:
1) the weeknumber is not correct
2) you should also be able to get the iso Year because this can be different from the year.

I hope this helps in getting a better world....
