Really simple comment for phpMyAdmin. Trying to install it on XP with MySQL 4.1 & Apache2. Setup the php.ini & httpd.conf file OK, php files rendered correctly all was going well. Set the path to my c:phpext dir and tried restarting but, kept getting errors:
"unable to load dynamic library 'c:phpextphp_mysql.dll'"
Turns out that unless you copy libmysql.dll from the php root dir into c:windowssystem32 it won’t work.
