If you have a large size database dump of MYSQL database to your website .You will face a problem when your try to import it with regular way which is usually phpmyadmin , you will get timeout , or stay hours .To avoid this you can it by easy way that I have already tried.
Using a php script file called BigDump .
You have first to edit this script put the database server , database name , database user and the password . Then you upload it to your server , and upload beside it the your database script (**.sql). (you use your FTP account ) .

To get it :
