You really have not given us sufficient information to help you.
First, can you connect to your MySQL database from the command line i.e.
mysql <database> -u <username> -p <password>
If you are connecting to a different host you will have to add a "-h <host>" option as well.
Have to configured your php.ini file to contain the right variables and values so that your PHP scripts can access the database?
I can connect to my MySQL database,But i don't know how configure the file "php.ini".
