it seems this is a very inactive forum. I solved my problem. Just in case anyone interested in the same practice, here is the solution:

configure PHP work with MySQL. mainly change the php.ini file
extension_dir = "C:\php"
uncomment the ";" for those mySQL related DLLs *mstring.dll, *mysql.dll in the extension section. (some solution requires put the libmySQL.dll into system32 directory);

then the MLF is working on my XP based environment.
