Help a Norwegian student!

When I'm trying to open phpMyAdmin/index.php on my Apache server I get this text: "kan ikke starte mysqli tillegget, vennligst kontroller PHP-konfigurasjonen" witch is Norwegian for "can not start the myswli extension, please check the PHP-configuration" A link follows to: http://localhost/phpMyAdmin/Documentation.html#faqmysql -> "[1.20] I receive the error "cannot load MySQL extension, please check PHP Configuration". To connect to a MySQL server, PHP needs a set of MySQL functions called "MySQL extension". This extension may be part of the PHP distribution (compiled-in), otherwise it needs to be loaded dynamically. Its name is probably mysql.so or php_mysql.dll. phpMyAdmin tried to load the extension but failed. Usually, the problem is solved by installing a software package called "PHP-MySQL" or something similar." How do I solve this problem??? --
