Missing MySQL in PHPinfo on Ubuntu Linux

[gustax]

I am working on a newly built Ubuntu server with Apache2, MySQL 5 and PHP 5.3.2 . It seems something is incomplete in the configuration. When I call phpinfo() there is no MySQL section in it. However, the "Additional .ini files parsed" section shows "/etc/php5/apache2/conf.d/mysql.ini, /etc/php5/apache2/conf.d/mysqli.ini, /etc/php5/apache2/conf.d/pdo.ini, /etc/php5/apache2/conf.d/pdo_mysql.ini "In my research I have seen references to uncommenting an extension line in the PHP .ini file, but I don't see any line like that in my .ini.I have been using MySQL from a remote GUI for a week with no problems, so I know the database install is fine. PHP runs completely normal except for not talking to MySQL.Any suggestions would be greatly appreciated.Thank you for taking the time to read my question.Paul
