For some reason there aren’t any PDO packages for PHP 5 on Ubuntu 6.10. They’re pretty easy to install from PECL but you might need to install the dev version of your database client libraries. Below is what I had to type to install PDO with the MySQL driver.
% sudo apt-get install libmysqlclient15-dev % sudo pecl install pdo % sudo pecl install pdo_mysql
You then need add the following to the end of your php.ini file(s). Depending on which version of PHP you installed they’ll be /etc/php5/apache2/php.ini, /etc/php5/cgi/php.ini and /etc/php/cli/php.ini.
