I can't work with Mysql

[Anon]

Hi, I am working with php 4 and mysql 3.23 on a linux mandrake server. I have a problem, I made a class in php to use mysql, I used it with Windows and it worked ok, but when I use that class with Linux it doesn't work, when I use mysql_select_db appears a warninhg message: Supplied argument is not a valid MySql result in /path/file.php (this is the class file).

I don't know what to do!!!!!!!!!!!!!

Bye.

it would help if we could see a sniplt of your code however I am guessing that you need to do a
mysql_connect("host","username","password");
mysql_select_db("databasename"); because you are now on a more secure system
