On proper servers
If you have a proper Web hosting provider then you probably have some form of control panel. Within that is probably a menu entry for database administration. That is probably PHPMyAdmin. Different servers may have slightly different versions but the basics stay much the same. If you do not have a control panel try:
Replace yourserver.com with the correct address of the server. You should be asked for a username and password and this should be the ones you used when you connected to the database using PHP.
Both localhost/phpmyadmin and 127.0.0.1/phpmyadmin should work. By default you will not need a password as XAMPP is not secure.
The front page
Once started you should see a front page with:
- the name of your server and the database server port address at the very top
- a range of tabs just under that
- some general settings and information in the centre
- a list of databases on the left
Check the settings but only one probably needs explanation. The server's connection collation is what set of text characters to use in queries. If utf8_general_ci or utf8_general_mysql500_ci are selected then leave it as it is. If not consider changing. These two provide all symbols for most character-based languages used (so not languages such as Mandarin or Kanji).
