Description:
------------
I'm using the "adler32" algorithm of the PHP hash() function.  The result that I get has the byte-order reversed from the result I get when doing the same hash on Python.

From the Python interpreter:
>>> import zlib
>>> hex(zlib.adler32('abc',1))
'0x24d0127'

I saw that a bug addressed this same thing for the crc32 algorithm, but what about adler32?

Reproduce code:
---------------
<?php
   echo hash("adler32","abc");
?>


Expected result:
----------------
24d0127

Actual result:
--------------
27014d02
