Hi -
I'm trying to get authorize.net SIM functionality in my site, and am having a bit of trouble.
I need to return this value from a function:
(bin2hex (mhash(MHASH_MD5, $data, $key)));
From what I understand, mhash support needs to be added at compile time for PHP. Is this function enabled on Hostony servers?
Also, if anyone has any tips or links to tutorials on making authorize.net work, I'd be grateful.
Thanks
