I'm currently running the latest versions of Apache, MySQL and PHP, and I've set my firewall to allow all requests on port 3306(The port I set my MySQL to watch for requests from), but I keep getting an error of: Can't create table '.\moviesite\movietype.frm' (errno: 121) when doing the chapter 3 exercises in "Beginning PHP5, Apache, MySQL -Web Developement". It can write the database perfectly, but it can't seem to write the tables.

I can write the tables though perfectly if I write them directly from MySQL under either the admin or the exception I set, it simply will not write the tables in the database when I request it through PHP. I am quite stumped on what to do and any help would be grealy appriciated. Thank you for your time.

You may try these things:
$host="localhost";
$host="localhost:3306";
$host="127.0.0.1";
$host="127.0.0.1:3306";
or specify IP lieu 127.0.0.1
As PHP manual says $host can b ":/path/to/socket" for UNIX it is perhaps ":/tmp/mysql.sock" I'm not sure for Windows. Try staus at your mysql prompt and see my.ini ( or mysql.ini ) file for information about TCP port MySQL is using. I hope, I've b'n helpful.

I found, I'm able2connect MySQL daemon, if I use $host=":anything";
where anything can be NULL or anything; surprised ;)

I've found out just what the error is, but I can't seem to find out how to fix it. The error of 121 actually corresponds it having the ability to write the table, but unable to write it as it states there is currently another instance of that table in existance;
"MySQL Error Code 121: Duplicate Key On Write Or Update"
Source: C:\mysql\bin\perror 121

The odd thing is, each time I get an error that it can't write the table, I delete the entire database that it's writing to(as there's nothing else there), yet that error still appears each time, for each table(It can write the base table perfectly fine, but the movietype and person tables afterwards, if added into the code, return the error). Any idea on just what to do? O.o
