I have encountered a problem that has stopped me cold in the Learning MySQL book. I went to that website and tried to register as a new user, but it gives me a 'New user Creation error/security code is incorrect" error. (The page has no place to enter a security code.)
Problem: I did the standard XAMPP installation on a WinXP PC as mentioned in the book. I went through exercises up to page 407, and then got the 'call to undefined function mysql_connect. I checked the mysql directory, and found it had no lib/, Docs/, or include/subdirectories. I then went to mysql.com, tried an installation of MySQL on its own (using port 3307) which failed to start the service. I then copied the three missing subdirectories to the xampp/mysql directory, but got the same error message when I tried to run query_artists.php.

Sorry for the delay in responding.
Did you see the note at the bottom of page 407 that says to make sure your PHP installation has the MySQL libraries installed. You might try reinstalling PHP on your computer. If you can't get this figure out, send me an email at firstname.lastname@example.org and we'll get it worked out.
