Where can I download MySQL for Windows XP for free?

I'm trying to learn MySQL and PHP, but I need these programs on my computer in order to do so. I know that it's open source, but where can I get a good version that meets the above expectations.

1. Mysql 5.0 http://dev.mysql.com/downloads/mysql/5.0.html#win32 PostgreSQL has more features http://www.postgresql.org/ SQLite is modular and clean - it is very popular especially with embedded systems. http://www.sqlite.org/ Firebird is not as popular http://www.firebirdsql.org/ And Of course MS SQL server Express - 2008 will be released soon http://www.microsoft.com/downloads/details.aspx?familyid=220549b5-0b07-4448-8848-dcc397514b41&displaylang=en
