Yii and functions

Hi everybody.

Sorry for my english but i’m french.

I had install a library (spplus) for a new bank paiement. I’s correctly installed. I can see it with phpinfo();

So when i call this function calcul_hmac(), its doesn’t work. Why ?

Have you a solution ?

Thank you a lot

You should really read the documentation that comes with that library to see how to use it…
