Hello PHP developers,

I am a begining developer, and I am trying to setup the payment gateway from authorize.net using PHP.

 

I found a very good tutorial and read through the explanation also download the codes.

 

However, it does not seem to be working....I am wondering if I didn't do it correctly. I don't know if PHP talented developers out there could show me the correct ways, or tell what was wrong with the code I added....

 

<code>

class Authnet

{

private $login    = "7989SeRGCRr7";

{

if (self::$instances == 0)
