two mysql installations php_mysql.dll extension and libmysql.dll question

Hello PHP community, This question may be more for the MySQL community. If so, my apologies, please let me know. I am using php v 5.2.6. I have two versions of MySQL running on my server (windows xp home sp3). MySQL v6 is running on localhost:3306 MySQL v5.0.41 is running on localhost:3307 I have two installations of phpmyadmin (latest version 3.0.1.1) to manage both of these (i am running a local apache 2.2 server on the same machine on port 8080). Let's call these two installations phpmy5admin and phpmy6admin. I am able to login and create tables on both versions of mysql. Thus, i suspect the installation of both of these is okay. When i view both phpmyadmin installations it gives me the correct corresponding mysql version number on the homepage. However, the phpmy6admin gives me a warning saying: "Your PHP MySQL library version 5.0.51a differs from your MySQL server version 6.0.7. This may cause unpredictable behavior." When i copy the libmysql.dll from the mysql 6 installation directory into the php directory i get a pop up saying apache must shutdown when any php script invokes the mysql module. my windows path variables have C:\php;C:\Program Files\MySQL in that order. my mysql installations are at C:\Program Files\MySQL\MySQL Server 5.0 C:\Program Files\MySQL\MySQL Server 6.0 I do suspect the c:\php is being read first, as when i change the libmysql.dll in this folder, i experience different results. I do not have any libmysql.dll files in my system path. My question are: 1) Is there a libmysql.dll for version 6? If so, where do i get it? 2) Does libmysql.dll for version 6 only function properly with an updated php_mysql.dll extension? If so, where do i get this updated extension? 3) If I get the correct library for version 6 working, will i then have issues running version 5? 4) Perhaps I can ignore the warning? (i don't like this option ;) Thanks for helping me, dK
