Cybercash example not working

[Anon]

Implementing CyberCash, I am having trouble understanding Nathan's examples at http://www.phpbuilder.com/columns/nathan20001225.php3

I got the first example to work fine. But integrating MySql with his second step is a total puzzle for me.

• Where does he open the MySQL connection?
• Is the following pseudo-code:
  if(mysql("your_db", $insert) == false){
  mail('[e-mail]',
  'Cyberauth Database Log Error','', $insert);
• If not, how do you connect to the db?
• Why did he use $db as a variable? $db is usually reserved for something like,
  $db = mysql_connect("localhost", "root");
  mysql_select_db("mydb",$db);
  $result = mysql_query("SELECT * FROM employees",$db);
