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
