I got a little confusion about mysql and php

hi, I m a newbie programmer and has just started working on php, i m not actually having much problem in it as because i have backgroud of C/C++ and vb and ASP and Pascal etc. I have a little confusion , may be it is gonna be a cheap question the question is as follows 1 - I have a mysql database on my local server on which i m trying php scripts. now i m gonna upload this site, I found out a function of mysql through which i m going to create the mysql db on the sever with phpscripts which is ( mysql_create_db() ) but i want to write my scripts as follows if ( database doesn't exists ) create db; 2 - and the other thing which is actually about mysql, which is how do i set different database passwords to different database. as because in my server ( win 2000 ) there is only one password which i use when using mysql_connect() fucntion --------------------------------- Do You Yahoo!?
