Serious problem about Pdo_Mysql extension

HI all
i have a big problem in installing Piwik
the error is that
"You need to enable the PDO and PDO_MYSQL extensions in your php.ini file. "
but even after i write
extension=pdo.so
extension=pdo_mysql.so
in php.ini i still have this problem!
and the server admin doesn’t know about Pdo_Mysql extension! style_emoticons/<#EMO_DIR#>/sad.gif
please help me!!!

Your system may simply not have those extensions.

You could ask your admin to rebuild php with those extensions enabled or find another host.

is there another way???

Self-hosting is another option.

There are also third-parties working on (or interested in) Postgresql and MySQLi forks/ports.

is it possible to install piwik on a server and use this for another site on another server?

Yes.
