Well they are just values in an array. There is no real reason to turn off persistent connection because PHP's mysql_connect function automatically makes a non-persistant connection. If you have any questions about persistent connections you can read about them here. As for the driver I am not sure. It almost looks like he is using a function that is designed to connect to any type of database and is a lot more open ended. However mysql_connect works fine and already defaults to all of those values so there is no real reason to set them if you plan on using that.

Thanks. I got it.

It looks pritty good, same as mine basically!

I don't think there's any improvement you can do security wise, but when your doing your mysql_query's use sprintf with mysql_real_escape_string (read up on it closer to the time) I think it makes the query more secure.

Thanks enough!!!

config.php or db.inc.php whatever its name is not important. For example: If filename is config.php, type the url of the config php, and you will see a blank page. You will not see the source codes, so filename is not important, I think.

Thanx guys for the info but a newbie like me would not jump into the config file. I need to start from scratch. I have google php tutorials but I keep getting the ones that are base on assumption I've already installed php or I need help with some trix on top of the basic php knowledge that I have. I need tutorials that will take me from the moment I double-click my php installer to the moment when I can say I have configured my site and php, apache and mySQL are now working in harmony. By the way my site is not on my rig. It's hosted by Trap17.
Can anyone point me to such resources? Pliz!

Its too clear now!!!
