"PHP USED" and missing the MySQL extension

[bigdigillc]

I keep waking up to my server being down with the error message "Your PHP installation appears to be missing the MySQL extension which is required by WordPress. KLOXO". I don't know if it is related, but I also can't select "PHP USED".

Check your php module with 'php -m' (for 'php branch') or 'phpXYm-cli -m' (change XY to 5.2-7.0; for 'multiple php').
