Check the example in the online documentation page.
http://www.php.net/manual/en/function.mysql-select-db.php

It's not the perfect way to do it. I would suggest you used try/catch
and throw an exception, the catch would tell the user that there is some
issues (do not show what went wrong, as that can be used to hack your
site), keep in mind to generate the theme outside the try/catch, this
way all pages will look nice no matter what happens.
Use syslog http://www.php.net/manual/en/function.syslog.php
to log what went wrong, now you have somewhere to find all the errors
and without displaying it to the whole world.
