Converting Authorize SIM for PHP 5

[Guest]

I need some very important help.

Our host has upgraded to PHP 5.1 something.

This version of php does not come with Mhas, but just "hash".

The only affected part of our 3.17 store is the authorize.net SIM transfer.inc.php page. Can someone tell me how to convert the Mhash call to has?

Our store is broken until then.

I'm guessing the part that needs changing is this (or more)

// compute HMAC-MD5

// Uses PHP mhash extension. Pl sure to enable the extension

function hmac ($key, $data)

{

return (bin2hex (mhash(MHASH_MD5, $data, $key)));

}

// Calculate and return fingerprint

// Use when you need control on the HTML output

function CalculateFP ($loginid, $txnkey, $amount, $sequence, $tstamp, $currency = "")

{

return (hmac ($txnkey, $loginid . "^" . $sequence . "^" . $tstamp . "^" . $amount . "^" . $currency));

}

"Mhash" is available in PHP5.

http://us2.php.net/manual/en/function.mhash.php

It's likely your host forgot to enable this extension when they upgraded.

Maybe, maybe not.

http://us3.php.net/mhash

says it was dropped as of PHP 5.3.0

But if Websurfer's host told him PHP 5.1.x, then it should still be there.

I do not know what the differences in the documentation between:

http://us3.php.net/mhash

and

http://us3.php.net/manual/en/function.mhash.php

I guess http://us3.php.net/mhash is an introductory overview of the whole mhash() library while http://us3.php.net/manual/en/function.mhash.php describes the core function itself.
